Claims

[Claims for Utility Model Registration] (1) Two reference plates sandwiching a laser active medium therein and firmly connected to each other at both ends of three or more rods, and a mirror included in the reference plates; two retaining plates installed adjacent to each other, three or more springs that connect the reference plate and the retaining plate to each other and apply a force in a direction to bring them closer together; A laser resonator comprising three or more screws that respectively pass through the springs and contact the reference plate to adjust the distance between the holding plate and the reference plate. (2) The spring is formed into a closed shape such as a circle, an ellipse, or a diamond by cutting a cylindrical pipe or bending or rolling a plate, and the shape is approximately symmetrical with respect to the screw. A laser resonator according to claim (1) of the utility model registration claim. (3) The three springs are arranged so as to form an L-shape by virtually connecting lines, and the orientations of the springs are such that the orientations of the two springs at the two tips of the L-shape are orthogonal to each other, Utility model registration claim (1), characterized in that the springs in the L-shaped bent portion are arranged in an intermediate direction between the two spring directions or in a direction perpendicular to the intermediate direction. laser resonator. (4) The above spring is formed by rolling or bending a tanzaku-shaped plate, overlapping the two ends of each other, and fastening the overlapping portions together to a reference plate or holding plate with screws. A laser resonator according to claim (1) of the utility model registration, characterized by:
