ABSTRACT:
A laser apparatus having an optical resonator composed of two end adjustably mounted mirrors positioned at each end of a YAG laser rod. In order to obtain mechanical stability and protection from the environment, concave mirrors having a radius of curvature of less than one meter are each installed in the mount. The mount includes a mirror cell which is preloaded into the mount housing using a generally truncated cone or belville washer shape as a spring. The center of the mirror is gimbaled about a bearing in the mirror cell. Once of the mirror is aligned, it is cemented in position. Thus, the mount combines a short radius of curvature mirror to reduce the sensitivity to optical and mechanical perturbations with a mount to provide mechanical stability in a high-shock environment.
