A resonator frame is fixedly formed with a plate 3 so as to maintain a predetermined interval between the resonator frames, a mirror holder 5 is attached to both ends of the rod of the resonator frame via disc springs 8, and a mirror holder 5 is attached to the mirror holder 5. Mi2-6 constituting a fixed laser resonator
Contains. The alignment of the mirror 6, that is, the 72-inch position of the mirror holder, is achieved by the elastic force of a disc spring 80 provided at the tip of the rod 2 of the resonator frame and the pressing force of the nut 9, as shown in FIG. There is. Note 4
7 is a nut that fixes the plate 3 to the rod 2, and 7 is a nut that holds the disc spring 8.

いう欠点があった。(Problem to be Solved by the Invention) The conventional method for attaching the mirror holder to the resonator frame is through an 8-t disc spring to make the 72-instance of the mirror holder easy. If the mirror holder, that is, the optical resonator mirror 2-, is not held properly and vibration or impact is applied in the vertical or leftward direction, the mirror holder, that is, the mirror holder for the optical resonator 2-, will be displaced, and the mirror holder 2-
The drawback is that the laser output changes depending on the alignment.

In a gas laser oscillator that has a Mitsu holder provided at both ends of a resonator frame and a mirror attached to the mirror holder, one end is fixed to the Mitsu holder between the mirror holder and the plate of the resonator, and the other is fixed to the Mitsu holder. It is characterized by a leaf spring whose end is fixed to the grate.

変動が抑えられるという利点を有する。(Example) Next, the present invention will be explained using the drawings. The plate 3 and mirror holder 5 are fixed to the plate 3 and the mirror holder 5 with screws via fixing bases 11 and 12 made of Aj, etc. The plate spring 10 is displaced in the direction of the laser axis. On the other hand, since the leaf spring 10 is fixed to the plate 3 and the mirror holder 5 via the fixing bases 11 and 12t, there is no vibration or impact in the vertical and horizontal directions perpendicular to the axis. The mutual positional relationship between the plate and the mirror holder does not change when the mirror holder is applied.Therefore, the mirror holder, that is, the optical resonator mirror 2- is not displaced, and there is an advantage that fluctuations in the laser output can be suppressed.
