Description
WEAPONS SYSTEM HAVING AT LEAST TWO HEL EFFECTORS
The invention concerns a weapons system consisting of at
least two nergy laser (HEL) effectors (HEL = High
Energy Laser). The invention ns the system
structure of a weapons system with a plurality of, but
at least two, HEL effectors on an object, in particular
with regard to the aspects of system weight, volume,
integration concept and installation effort.
Inter alia, HEL effectors are used to protect movable or
stationary objects. A HEL effector is used to combat
different targets. Multiple HEL effectors can be targeted
at one target or multiple s at the same time. This
can include static targets such as mines, IEDs
(Improvised Explosive Devices), etc., but also dynamic
targets, such as rockets, artillery shells or RAM
projectiles, etc. These s are then shed
and/or destroyed as part of the defense against the
threat. Small targets (Low, Slow & Small = LSS targets)
in ular can be more easily demolished or yed
by such a weapons system. LSS targets also include socalled
UAVs (Unmanned Air Vehicles), such as drones,
which are often used improperly for transporting
explosives.
Key components of a HEL effector include a laser source
and a beam guidance system. The beam guidance system can
house the sub-assemblies fine imaging system (FIS), fine
tracking system (FTS), telescope and, if necessary, at
least one adaptive optical system (AO). Well-known laser
sources are gas lasers, such as C02 lasers, as well as
solid state lasers, such as diode lasers, fiber lasers,
etc.
Currently, fiber lasers, a special form of diode-pumped
solid state laser, are red as laser sources for HEL
effectors e of their advantages. The high-
performance fiber laser includes one or more pump
sources, such as one or more pump diodes. In the fiber
laser, the pumping light is coupled into an active fiber
and converted into laser light of very good beam quality.
High-performance fiber lasers are either constructed as
pure oscillators (an active fiber with a resonator) or
as multi-stage oscillator–amplifier systems so-called
MOPA (MOPA = Master Oscillator and Power Amplifier). In
a MOPA structure, the power of an oscillator is coupled
into uent amplifier levels e fibers) and
boosted to higher power. The laser light is then d
via the beam guidance system to a target etc. to attack
the target. All optical components are usually connected
to optical fibers ve transport fibers). In
addition, there are the power supply and cooling system,
which supply and cool the pump source and the master
oscillator power amplifier of the dual laser
sources. The power supply and cooling system can be part
of the laser source.
Due to non-linear processes that can occur in fibers at
high power levels, the s of the ready-made fibers
must be limited, for example between the MOPA or
oscillator and the beam guidance system at high power
levels in the multi-kW range. Depending on the power,
fiber parameters, fiber structure, wavelength, etc., a
maximum possible fiber length of a few meters can result.
The M2 beam y is also a decisive factor for the
effect of HEL effectors. The beam quality value M2 should
be as low as possible, preferably less than 2.
HEL effectors, like other weapons systems, can be
supported on a fixed or movable platform. Weapons
stations are also referred to as a platform. Said
platforms, for their part, can be attached to stationary
objects (e.g. houses, bunkers, containers, etc.) or
moving objects (e.g. vehicles on land, in the air and at
sea, containers, etc.). For larger objects, multiple
platforms are often used. On a vehicle, ally on a
maritime , such as a ship, the platforms are often
disposed on the starboard and/or port side. Other
platforms may additionally or atively be mounted
on the bow and/or on the stern.
The advantage of a HEL effector over conventional
effectors (conventional weapons) is, among other things,
a high hit accuracy and a delay-free effect. There is no
need to take any prediction into account. There are also
no muzzle s and almost no firing signatures.
Similarly, there is no limit on the operational
capability of the HEL effector due to a magazine
capacity.
In order to achieve the required radiation quality of a
HEL effector, the aim is also to accommodate the MOPA or
the oscillator very close to the weapon station or
platform.
The components of the HEL effector are housed in practice
in a compartment (chamber). This leads to the restriction
of deployment locations and the feasible maximum laser
power. Such a restriction has a negative effect on
maritime objects in particular.
A laser system for generating high or compact power
densities on the object is known from DE 10 2010 051 097
A1. The power is divided between several lasers or laser
s and geometrically mposed on the target, so
that a total power density of all the individual power
densities is achieved in total. As a weapon, the single
lasers or laser weapons form a weapons system to combat
an attacking object. Said laser weapons are aimed at the
object by means of coarse tracking and fine ng. The
laser weapons can be mounted on a moving or stationary
platform. According to the document, such lasers can also
be used as sing lasers for material processing, for
example at greater distances.
A2 describes a laser or laser weapon in
which a laser generation unit is positionally separated
from a telescope that is to be directed at the target.
While the telescope, together with a target detection or
tracking arrangement, is located on a mobile platform of
a mobile vehicle, the laser generation unit is fixedly
integrated within the mobile vehicle or a separate unit.
The functional connection between the ope and the
laser tion unit is made by means of an optical
fiber.
DE 33 18 686 A1 discloses a device for aiming a laser
beam. This device is designed to be able to pivot a highenergy
laser beam in a fixed parallel orientation with
the orientation of other s on a platform. The laser
source is disposed away from the platform. The laser beam
is transmitted to optical elements via deflection
mirrors.
DE 10 2012 015 074 B3 publishes a beam directing unit for
a laser weapons , wherein the beam directing unit
comprises a stationary/partly movable component and a
fully movable component. A target acquisition or target
tracking device as well as a telescope and an output
stage t are attached to the fully movable part. The
beam directing unit includes at least one laser
generation unit, which comprises at least one seed laser
unit and at least one pump laser unit. The seed laser
unit as well as the pump laser unit are ted to the
output stage element (e.g. an amplifier) using an optical
fiber. In the case of several pump laser units, the
individual laser powers are merged in a beam coupler and
also fed to the output stage element via an optical fiber.
This ensures that the mass on the fully movable part can
be reduced. The total weight on the object, on the other
hand, does not change.
It is the object of the ion to optimize the system
design in terms of the required mass, space requirements
and integration effort when using two or more HEL
effectors. It is an additional or alternative object of
the invention to at least provide the public with a useful
alternative.
The object is achieved by the features of claim 1.
Advantageous ments are revealed in the sub-claims.
In a first aspect of the invention, there is provided a
weapons system comprising at least two HEL effectors,
each with at least one beam guidance system, the at least
two HEL effectors comprising at least one jointly useable
power source comprising a light pump source, n the
at least one laser source is connectable to each of the
at least one beam ce systems by means of at least
one optical switching unit, wherein the at least one
optical switching unit can adjust and/or vary the beam
power of the laser light generated by the laser source,
and wherein the at least one optical switching unit can
divide the laser light between at least two outputs of
the at least one optical switching unit at the same time.
In a second aspect of the ion, there is provided
an object comprising the weapons system as outlined above
in relation to the first aspect.
The embodiments described herein are based on the idea
of not assigning all the key components of a HEL or
to every HEL effector. For example, not every HEL
or should have its own complete laser source, or
parts thereof. Rather, it is envisaged that this key
component, or parts thereof, will be jointly usable by
several HEL effectors. This key component, or parts
thereof, is/are defined as a shared component. In an
optimal implementation, a HEL effector only needs its own
key component, namely at least one beam guidance system
as an individual component. The individual beam guidance
systems may house the sub-assemblies of fine imaging
systems (FIS), fine tracking systems (FTS), telescopes
and, if necessary, at least one adaptive optical system
(AO). The jointly usable key component, or parts thereof,
is/are in turn connected to the individual key
component(s) of the HEL effector in such a way that the
operation of at least one HEL effector is guaranteed.
The embodiments described herein therefore propose to use
only one laser source or pump source for at least two HEL
effectors in a weapons system with at least two HEL
ors, which have at least one beam ce system.
The beam guidance s of the HEL effectors access the
common laser source or pump source. An optical tion
of the common laser source or pumped source to the beam
guides, directly or indirectly, is made by at least one
optical ing unit, so that at least one functional,
complete HEL effector is provided in the threat response
weapons system.
As a consequence of this idea, individual key ents,
or parts thereof, can be saved in the case of a plurality
of HEL effectors on an object. By saving individual key
components, or parts f, the total weight, space
requirement and integration effort of the HEL effectors
on the object can be d.
This idea is based on the knowledge that the accuracy,
precision and fast alignment of today's HEL effectors
make it possible to combat a target or even multiple
targets by a single HEL effector. There is no need for
all the HEL effectors attached to the object to be
functional at the same time.
In an embodiment, a plurality of HEL effectors, at least
two, consist of a jointly usable key component, the laser
source, and an individual key component, the dedicated
beam ce system. The laser source includes at least
one pump source with at least one pump diode, preferably
a plurality of pump diodes, as well as at least one MOPA,
alternatively at least one oscillator. A power supply and
cooling system can also be ed to the laser .
The central laser source is the key component of all HEL
effectors. The optical connections are realized using
optical fibers or free space. The laser source, which can
be used by several HEL effectors, can in turn be placed
centrally on the object. It should be noted that a
necessary beam quality is maintained during beam
transport.
An optical connection of the central laser source to the
individual beam guidance systems is carried out via at
least one optical switching unit. The optical switching
unit can be an optical switch or an optical switching
point. An optical switching point is characterized in
that it switches quickly, with angular precision and
always reliably. The optical ing unit should also
be designed to be able to divide the laser light between
at least two outputs of the l switching unit, even
at the same time. The distribution should be achievable
continuously or in l stages. There are at least two
stages to be provided, for example via end stops. The
laser light should be able to be divided from 0 to 100%.
The single HEL effector thus consists in a first
embodiment of a jointly usable laser source and at least
one dedicated beam guidance system. This creates the
ility that only the dual beam guidance system
of the respective HEL effector needs to be supported on
a platform as already defined. This le embodiment
is not favored, but it is technically feasible.
In a further, preferred ment the entire laser
source, i.e. with all components, such as pump source,
MOPA or oscillator, is disposed centrally. It can be
sufficient if only the pump source(s) of the laser source
is/are centralized. In addition to the dedicated beam
guidance system, a ted master oscillator +
ier (MOPA) or oscillator is assigned to each HEL
effector. Said MOPA or oscillator can then be disposed
in the vicinity of, even in close proximity to, the
respective platform, but can even be mounted on the
respective platform. Each amplifier of the MOPA or
oscillator can be optically connected to the pump source.
The master oscillator (MO) can be accommodated in the
vicinity of the pump source or the amplifier depending
on the length of the fiber. Other iers may also be
integrated am of the individual beam guidance
systems of the HEL effectors.
The optical switching unit, for its part, serves to
apportion the pumping power of the pump source to at
least two outputs of the optical switching unit. For a
plurality of pump sources, these can also be distributed
via the optical switching unit to at least two outputs
of the optical switching unit. The outputs of the optical
switching unit(s) for g power are in turn
associated with at least one input of the iers (PA)
of the HEL effectors, preferably by means of l
fibers. The division of pumping power should be carried
out uously or in multiple stages. In this case, at
least two stages are to be provided, for example via end
stops. The pump power should be able to be split from 0
to 100%. It is also provided that the division is possible
at the same time for a plurality of outputs of the optical
switching unit. A simultaneous division of pump power
between the amplifiers (PA) of the HEL effectors allows
several HEL effectors to be able to function at the same
time.
Alternatively, each pump source can be fed to the
dedicated optical ing unit thereof and apportioned
thereby to at least two outputs. Furthermore, a cascaded
arrangement of 2n outputs can be realized with the help
of a plurality of optical switching units comprising at
least two outputs.
In this embodiment, the individual HEL effector consists
of a y usable central pump source, as well as at
least one dedicated MOPA or at least one dedicated
oscillator and at least one dedicated beam guidance
system. The respective MOPA or oscillator of the HEL
effectors can be accommodated near the beam guidance
system of the HEL effector. A direct connection to the
platform together with the beam guidance system is also
conceivable.
The optical connection between the pump source and the
amplifiers of the MOPA or the oscillators is preferably
established via optical fibers. A free space version is
also possible.
The l connection of the central pump source to the
ators or the amplifiers of the MOPA is established
here too via at least one optical switching unit. The
optical switching unit can also be an l switch or
an optical switching point. By means of the optical
switching unit, a working line can result in this
embodiment: pumping unit - fiber (optical path) al
switching unit - fiber (optical path) - oscillator or
amplifier. When using a plurality of oscillators, the
outputs of the optical switching s) are connected
to a pump input (active medium) of the ator,
preferably by means of optical fibers. Even with a low
beam quality of the pump diodes, despite the high power,
an optical connection (fiber, free space) with a
significantly greater distance than a few meters can be
established between the at least one optical switch and
the amplifiers or oscillators. However, variations that
lack an optical path are also conceivable in this
embodiment.
Another option is to provide a commonly usable master
oscillator (MO) separately from the pump source instead
of the many individual master oscillators. The optical
connections between the pump source and the amplifiers
of the HEL effectors are implemented ing to the
above bed embodiment. The central master ator
provided can be located near the pump source, which
simplifies the power supply and cooling of the master
oscillator. The output of the master oscillator can be
switched to at least one input of the iers (PA) of
the HEL effectors by means of at least one further optical
switching unit.
Due to the low weight of the individual amplifier, it can
be supported directly on the platform with the beam
guidance system. This allows the good beam quality of the
amplifier to be coupled into the beam guidance system at
high power. ing on the output power of the master
oscillator, different permissible fiber lengths result
for the optical connection, e.g. optical fiber, between
the master oscillator and the amplifiers.
The individual HEL effector ts in this third, also
favored embodiment of a jointly usable central pump
source, a shared master oscillator (MO), dedicated
amplifiers (PA) as well as ted beam guidance
systems.
An additional controller can also be used to determine
which of the MOPA, amplifier (PA) or oscillator(s) to be
added should be ed with what percentage of laser
or pumping power. Thus, for each HEL effector, the beam
power of the laser or pump source can be adjusted and/or
varied. Said percentage n can be controlled by
means of the optical switching unit(s).
The l switching units, for their part, can be
spaced apart from the central laser source or the l
pump source and, if necessary, from the central master
oscillator (MO). Due to the low beam quality of the pump
, an optical connection (fiber, free space) with a
significantly longer distance than a few meters can be
implemented here, ally between the optical
switching units and the amplifiers or ators. With
poorer beam quality, the beam transport takes place in
fibers with a larger core diameter at a reduced
intensity, so that non-linear processes are used to a
reduced extent.
The optical switching unit also allows the laser source
or pump source to be separated from the other components
of the HEL effectors. The HEL effectors can be changed
to a safety state by means of the optical switching
unit(s).
Of course, other central laser sources, pump sources and
other central master oscillators, etc. can also be
provided as jointly usable key components. This makes it
possible to create a redundant system. Also, multiple HEL
effectors can be grouped together into groups that can
then be operated in el.
The use of a laser source, alternatively a pump source,
etc., for a ity of HEL effectors allows the total
weight on the object to be reduced. The decentralized
arrangement of the common central laser source or pump
source etc. for the plurality of HEL effectors also
creates the possibility of placing them on or in the
object and protected from environmental influences.
In addition to the weight saving, the present invention
gives a further advantage. The laser source, pump source,
possibly the central master ator power amplifier
(MOPA) or the central master ator (MO) or central
oscillator can now preferably be accommodated within the
object, e.g. in the hull of a ship or vehicle. These
components are no longer t to the environmental
requirements on the object. A positional separation also
gives another age. In this way, the individual
components can be led in smaller spaces on the
object, for example in recesses.
Especially on a ship, saving components is a huge win.
Such scaling down of components makes the use of HEL
effectors on such s possible and also financially
practicable. The HEL effectors can be offered more costeffectively.
Existing platforms, such as conventional
effectors, can also be used. For example, the platform
of a naval light gun, etc., can be used to accommodate
individual components of the HEL effectors. However,
these advantages also arise for other vehicles on land,
sea and in the air and can be transferred to other
objects.
The mode of operation is generalized as follows:
If a target or threat is detected, for example by means
of a weapon delivery system, it is determined which of
the beam guidance system(s) of the HEL effectors on the
object can provide the best possible defense against or
lization of the threat as quickly as possible. Such
procedures are known to the person skilled in the art.
The weapon delivery system then s which beam
guidance system(s) to use. Alternatively, this can be
carried out by an operator. As a result of this decision,
an optical linking of the ed beam guidance
system(s) is carried out as described above. The
switching of the optical switching unit(s) can be carried
out pneumatically, hydraulically as well as electrically
or electro-optically, although other possibilities are
not excluded. The switching is controlled by the central
control unit.
In this specification where nce has been made to
patent specifications, other external documents, or other
sources of information, this is generally for the purpose
of providing a context for discussing the features of the
invention. Unless specifically stated otherwise,
reference to such external documents or such sources of
ation is not to be construed as an admission that

general knowledge in the art.
The invention will be explained in more detail on the
basis of an exemplary embodiment with a drawing. In the

wherein a laser source can be used for at least
two or more HEL effectors,

in a schematic block image representation,
wherein at least one pump source is used for
at least two or more HEL effectors,
Fig. 3 shows a third embodiment r to Fig.2,
Fig. 4 shows another embodiment of the inventive idea
in a schematic block image representation
Fig. 5 shows a sketched entation of a e
structure for a division of laser power.
In Fig. 1 a laser source 1 as well as at least two beam
guidance systems 2.1, 2.2, 2.3 are represented as key
components of several, at least two, HEL effectors 5.1,
.2, 5.3.
An imaging system is defined as the beam guidance system
2.1, 2.2, 2.3. This can be built according to DE 10 2010
051 097 A1. Beam ce systems with a different
structure are also conceivable. The laser source 1
contains at least one pump source 10, which is formed by
at least one pump diode. The pump source 10 can be
supplied with electricity and cooled by a power supply
and g system 11. Said power supply and cooling
system 11 can be a component of the laser source 1.
Associated with the laser source 1 is a master oscillator
power amplifier (MOPA) 12 (e.g. a seed laser +
ier), which can be placed therein. Alternatively,
an oscillator (single resonator) 13 can be used.
The individual beam guidance systems 2.1, 2.2, 2.3 of the
HEL ors 5.1, 5.2, 5.3 can be connected by means of
an optical ing unit 4 to the laser source 1. HEL
effectors 5.1, 5.2, 5.3 thus have a common laser source
1 and individual beam guidance systems 2.1, 2.2, 2.3 as
their key components.
The optical switching unit 4 can be an optical switch or
an l switching point. The optical switching unit
comprises at least one input and at least two outputs.
The optical switching unit 4 should be designed to be
able to split the laser power (optical power) generated
in the laser source 1 for the beam guides 2.1, 2.2, 2.3
of the HEL ors 5.1, 5.2, 5.3. The division can be
carried out continuously or in multiple stages. The
optical power can be divided between 0% and 100%. It is
also provided that it is possible to split the optical
power at the same time, so that a plurality of beam guides
2.1, 2.2, 2.3 of the optical switching unit 4 can be
supplied with optical power at the same time. For
example, if the optical switching unit 4 comprises only
two outputs, several optical switching units 4 can be
used to build a cascade, by means of which a division of
the laser power between the beam guides 2.1, 2.2, 2.3 can
be realized (fig. 5).
The output of the laser source 1 is optically (15)
connected to an input of the optical switching unit 4,
ideally by an optical fiber. A free space link is also
possible.
The multiple outputs of the optical switching unit 4 are
fed to the inputs of the beam ce systems 2.1, 2.2,
2.3 by means of optical connections 15. The switching of
the l switching unit 4 is controlled by an
additional controller 6.
The beam guidance systems 2.1, 2.2, 2.3 can in turn be
ted on a platform 7, 8, 9. The platforms 7, 8, 9,
for their part, are preferably movable, so that the beam
guidance s 2.1, 2.2, 2.3 of the HEL effectors 5.1,
.2, 5.3 can be pivoted in azimuth and/or elevation. This
allows the HEL effectors 5.1, 5.2, 5.3 to be aimed at the
threat(s).
The HEL effectors 5.1, 5.2, 5.3 are formed in a first
embodiment by the common l laser source 1, the
optical switching unit 4, the ted beam guidance
systems 2.1, 2.2, 2.3 as well as the optical connections
, ideally optical fibers.
A plurality of HEL effectors 5.1, 5.2, 5.3 can be combined
into a weapons system 100.
The manner of operation is as follows:
After a threat or threats has/have been detected in a
conventional way, it is determined by a weapon delivery
system, e.g. a fire control system (not shown in more
detail), which beam guidance system 2.1, 2.2, 2.3 would
achieve a good e against the threat. In the event
that the beam guidance system 2.1 of the HEL effector 5.1
is determined, this information is given to the
controller 6. The controller 6 in turn switches the
optical switching unit 4 so that the optical power of the
laser source 1 is transmitted via the switched output of
the optical ing unit 4 and the input of the selected
beam guidance system 2.1. said beam guidance system 2.1
radiates the optical power against the threat.
The l power of the laser source 1 can also be output
to the beam guidance system 2.1 to a d extent by
the optical switching unit 4 ed to less than 100%).
Should the fire control system stipulate that more than
one beam guidance system 2.1, 2.2, 2.3 is used for
e, the optical power of the laser source 1 will be
split and this optical power will be divided between the
inputs of the beam guidance systems 2.1, 2.2, 2.3
ated or defined for the defense. From these, the
optical power can then be radiated to avert the threat
against it. In doing so, beam guidance systems 2.1, 2.2,
2.3 can be jointly aimed at one threat, as well as at
different threats.
Fig. 2 and fig. 3 show a variant of the solution according
to fig. 1 as a second exemplary embodiment. Unlike the
solution according to fig. 1, in the second exemplary
embodiment the MOPA 12 or oscillator 13 is removed from
laser source 1. A central pump source 10 is provided that
generates the required pumping power for all the HEL
effectors 5.1, 5.2, 5.3.
According to fig. 2 instead of a central oscillator 13 a
plurality of oscillators 21.1, 21.2, 21.3 are ed
for the HEL effectors 5.1, 5.2, 5.3. An output of the
respective oscillator 21.1, 21.2, 21.3 is fed to the
associated beam guidance system 2.1, 2.2, 2.3. The
optical switching unit 4 provides the oscillators 21.1,
21.2, 21.3 with pumping power of the pump source 10. The
optical switching unit 4 is switched as described for
fig. 1.
The MOPA 12 can also be d into le MOPAs 22.1,
22.2, 22.3 (fig. 3). Said MOPAs 22.1, 22.2, 22.3 can be
arranged near rms 7, 8, 9. An output of the
amplifier of the MOPA 22.1, 22.2, 22.3 is directed to the
associated beam guidance system 2.1, 2.2, 2.3. The supply
of pumping power of the pump source 10 to the amplifiers
of the MOPAs 22.1, 22.2, 22.3 is carried out by means of
the optical switching unit 4. The manner of operation and
the switching of the optical switching unit 4 are carried
out as described for fig. 1.
The HEL effectors 5.1, 5.2, 5.3 are formed in these
embodiments by a common pump source 10 (plus a power
supply and cooling device 11), an l switching unit
4, oscillators 21.1, 21.2, 21.3 and MOPAs 22.1, 22.2,
22.3 and their dedicated beam guides 2.1, 2.2, 2.3 as
well as the optical connections 15, y optical
fibers.
Fig. 4 shows another solution variant of the inventive
idea, based on fig. 3. The exemplary embodiment according
to fig. 3 shows the variant according to which the entire
MOPA 22.2, 22.3 can be mounted separately from the pump
source 10 close to the pump source 10 or the beam guidance
systems 2.1, 2.2, 2.3.
ingly Fig. 4 is now a further step in the
implementation of the idea in that said MOPAs 22.1, 22.2,
22.3 are implemented in such a way that a common master
oscillator (MO) 22 can be provided for the remaining
amplifiers .1, .2, .3. This in particular minimizes the
weight to be supported, since only the respective
amplifier .1, .2, .3 would have to be supported.
For this embodiment, another optical switching unit 14
is used, which, like the optical switching unit 4 for
pumping power, can also connect the central master
oscillator 22 to the dual amplifiers 1, .2, .3 at
the same time. Said optical switching unit 14 should be
able to meet the same requirements as the optical
switching unit 4. The optical switching unit 14 is
located between the output of the master oscillator 22
and an input of the amplifiers .1, .2, .3 for this and
switches the output of the master oscillator 22 to the
respective input of the amplifiers .1, .2, .3. r
input of the amplifiers .1, .2, .3 is reserved for
ing the pumping power of the pump source 10.
The HEL effectors 5.1, 5.2, 5.3 in this fourth version
are provided by a central pump source 10, a central master
oscillator (MO) 22, the individual dedicated amplifier(s)
.1, .2, .3, which are aligned with the dedicated beam
guidance system 2.1, 2.2, 2.3, as well as the optical
connections 15, ideally optical fibers.
It is understood that within the scope of the inventive
idea, more than one s system 100 will also be
ed to the object, e.g. a port weapons system or a
starboard weapons system, etc.
