Connect to. In addition, the (+) terminal of the laser power supply 1' on the (-) side is connected to the ground, and the (-) terminal is connected to the cathode 6 of the laser tube 5 through the external coaxial cord 3' and the high voltage connector 2' attached to the housing. Connect to.
In addition, high voltage connectors 2, 2' and coaxial cords 3,
Connect the outer conductor of 3' to ground.

のカソード６側をリセプタクルとしている。 Therefore, two sets of (+) and (-) laser power supplies 1,
When a power input is applied to 1', a discharge starts between the anode 7 and cathode 6 of the laser tube 5, and the optical resonators 8 and 8' oscillate a laser to output a laser output 9. In addition, coaxial type high voltage connectors are normally used for the high voltage connectors 2 and 2', and in order to prevent incorrect connection, the laser power supply 1 side of the high voltage connector 2 is used as a receptacle, and the stabilizer resistor 4 side is used as a plug. Plug the laser power supply 1' side of the
The cathode 6 side of the receptacle is used as a receptacle.
ところで、高圧コネクタ２′のレーザ電源１′側

高圧にも耐えることが出来る。 By the way, if input voltage is applied to the laser power supplies 1, 1' without connecting the plug on the laser power supply 1' side of the high voltage connector 2' to the cathode 6 side of the laser tube 5,
Since the spatial distance between the core wire of the plug of the high voltage connector 2' and the external conductor is close to each other, approximately 5 mm, the output voltage of approximately (-)8KV of the laser power supply 1' causes dielectric breakdown, which occurs in the high voltage connector 2'. Damage to the plug and laser power supply 1'. Note that when the high voltage connectors 2 and 2' are connected normally, a Teflon insulating ring between the core wire of the receptacle and the outer conductor is inserted into the space between the core wire of the plug and the outer conductor to provide insulation. The creepage distance is approximately 20mm, and it can withstand high pressure of approximately 20KV.
本発明の目的は、前記欠点を改善するために、
高圧コネクタ２，２′が接続されていない状態で

ガスレーザ装置を提供するにある。 The purpose of the present invention is to improve the above-mentioned drawbacks.
When the high voltage connectors 2, 2' are not connected, input voltage is not applied to the laser power supplies 1, 1' to prevent dielectric breakdown of the high voltage connectors 2, 2' and breakdown of the laser power supplies 1, 1'. An object of the present invention is to provide a gas laser device.

In FIG. 2, the input power source is connected to the laser power source 1, 1' through the relay contact 12, the laser power source 1, 1' is connected to the laser tube 5 in the same manner as described above, and the external conductor of the high voltage connector 2 is connected to the power source section 13.
The outer conductor of the high voltage connector 2' and the outer conductor of the coaxial cord 3 are connected to the ground of the laser oscillator section 1.
4, and the outer conductor of the coaxial cord 3' is connected to the relay drive circuit 10 with the outer conductor floating above the ground. Further, the input power source is connected to the relay power source 11, one output end of the relay power source 11 is connected to the relay drive circuit 10, and the other output end is connected to the ground of the power source section 13. When the input voltage is applied, the output current of the relay power supply 11 flows through the relay drive circuit 10, the outer conductor of the coaxial cord 3', the outer conductor of the high voltage connector 2', the ground of the laser oscillator section 14,
It flows through the outer conductor of the coaxial cord 3, the outer conductor of the high voltage connector 2, and the ground of the power supply section 13, respectively, and closes the relay contact 12. Therefore, the input voltage is applied to the laser power supplies 1 and 1', and the input voltage is applied to the laser tube 5.
A discharge starts between the anode 7 and the cathode 6, and the optical resonators 8 and 8' oscillate laser, producing a laser output 9.
Output. Further, when the high voltage connector 2' is not connected, the output current of the relay power supply 11 is cut off between the plug of the high voltage connector 2' and the external conductor of the receptacle, and therefore does not flow to the relay drive circuit 10. Then, since the relay contact 12 remains open, the input voltage is
1' and no high voltage is generated. This may result in dielectric breakdown of the high voltage connectors 2 and 2' and damage to the laser power supply 1,
1' to prevent damage.

い。 In addition, in the description of the above embodiment, the laser power supply section 1
The positive output of No. 3 is connected to the housing-mounted connector, and the negative-pole side is used as a high-voltage cord extraction, but this should be reversed and, of course, the high-voltage cord and housing-mounted connector should be replaced on the laser oscillation side as well. Furthermore, it goes without saying that the external conductor that is lifted from the ground to create the relay drive circuit may be either a high voltage cord or a housing connector.
