Description
【発明の詳細な説明】 〔発明の目的〕 (産業上の利用分野) 本発明はレーザ共振器に係り、特にレーザ用ミラー保持
機構に関する。The present invention relates to a laser resonator, and more particularly, to a mirror holding mechanism for a laser.
(従来の技術) 従来は、第2図のように、ミラーマウントに設けられた
Oリング溝7にOリング3があってレーザミラー2がそ
の上に置かれ、押え金具6で押えてを固定してOリング
をつぶす。(Prior Art) Conventionally, as shown in FIG. 2, an O-ring 3 is provided in an O-ring groove 7 provided in a mirror mount, a laser mirror 2 is placed on the O-ring 3, and the presser metal fitting 6 holds the O-ring 3 in place. Then crush the O-ring.
(発明が解決しようとする問題点) この構造では次の問題点がある。(Problems to be Solved by the Invention) This structure has the following problems.
(1) ミラー面をOリングに当てるため、ミラー周辺
部にOリングの溝幅とその両側のスペースが要り、ミラ
ーの有効開口面積が小さくなる。(1) Since the mirror surface is brought into contact with the O-ring, the groove width of the O-ring and spaces on both sides of the groove are required in the peripheral portion of the mirror, and the effective opening area of the mirror becomes small.
(2) 真空グリースで湿潤したOリングを使うと、ミ
ラーの表面が汚れる。(2) The surface of the mirror gets dirty when an O-ring moistened with vacuum grease is used.
(3) ミラーの上からOリングを押しつぶすため、押
す力すべてがミラーにかゝり、ミラーがひずんだり、破
損するおそれがある。(3) Since the O-ring is crushed from above the mirror, all the pushing force is applied to the mirror, which may cause the mirror to be distorted or damaged.
(4) ミラーのマウント間にOリングがあるため、熱
伝達が悪い。(4) Heat transfer is poor due to the O-ring between the mirror mounts.
(5) Oリングが押しつぶし切れないとき、ミラーマ
ウントとミラーの位置関係が出ない。(5) When the O-ring cannot be crushed, the positional relationship between the mirror mount and the mirror does not appear.
(6) ミラーに対して内圧や外圧がかかると、Oリン
グのつぶれ代だけ、動くおそれがある。(6) When an internal pressure or an external pressure is applied to the mirror, there is a risk that the O-ring will move by the crushed margin.
(問題点を解決するための手段) 本発明では、第1図に示すように、レーザ用ミラーマウ
ント1にレーザミラー2が直接接するように配置され、
そのミラーの周囲に巻くようにOリング3が設けられて
いる。このOリング3は、このOリングだけを押えるO
リング押え4で押えられ、ミラーマウント1,ミラー2と
密接する。レーザミラー2はこのミラーのみを押えるこ
とのできるミラー押え5でOリング3を介することなく
固定する。(Means for Solving Problems) In the present invention, as shown in FIG. 1, a laser mirror 2 is arranged so as to be in direct contact with a laser mirror mount 1.
An O-ring 3 is provided so as to be wound around the mirror. This O-ring 3 is an O-ring that holds down only this O-ring.
It is pressed by the ring presser 4 and comes into close contact with the mirror mount 1 and the mirror 2. The laser mirror 2 is fixed by a mirror retainer 5 that can retain only this mirror, without using the O-ring 3.
(作 用) この結果、 (1) ミラー面にOリングを当てる必要がなく、Oリ
ング溝7が要らない。(Working) As a result, (1) It is not necessary to apply the O-ring to the mirror surface, and the O-ring groove 7 is not necessary.
(2) ミラーとミラーマウントを直接当てられる。(2) The mirror and the mirror mount can be directly applied.
(3) Oリング,ミラーを個々に別の力で固定でき
る。(3) The O-ring and mirror can be fixed individually with different forces.
(4) ミラーの位置が正確に出る。(4) The position of the mirror is accurate.
〔発明の効果〕 本発明によれば (1) ミラーとOリングが側面で接するので、Oリン
グ溝が要らなくなり、さらにスペースも不要で、ミラー
の有効開口面積が大きく取れる。[Advantages of the Invention] According to the present invention (1) Since the mirror and the O-ring are in contact with each other on the side surface, the O-ring groove is not required, and further, the space is not required, and the effective opening area of the mirror can be made large.
(2) Oリングはミラーの側面で接するため、Oリン
グを真空グリース等で湿潤した場合も表面が汚れること
がない。(2) Since the O-ring is in contact with the side surface of the mirror, the surface is not contaminated even when the O-ring is wet with vacuum grease or the like.
(3) Oリングをミラーとは独立に押しつぶすことが
できるため、ミラーに無理な力をかけることなく十分に
押しつぶすことができ、ひずまず破壊しない。(3) Since the O-ring can be crushed independently of the mirror, the O-ring can be crushed sufficiently without applying excessive force to the mirror, and it does not break without breaking.
(4) ミラーとミラーマウントは直接接するため、熱
伝導がよい。(4) Since the mirror and the mirror mount are in direct contact with each other, heat conduction is good.
(5) ミラーとミラーマウントが直接接するため、位
置精度が正しく出る。(5) Since the mirror and the mirror mount are in direct contact, the positional accuracy is correct.
(6) ミラーが変動要素のないもので固定できるた
め、内圧や外圧がかかった場合も動かない。(6) Since the mirror can be fixed with no variable element, it does not move even when internal pressure or external pressure is applied.
