The subject invention relates to a laser system where the length stability of the resonant cavity is important. Three unique mounting assemblies are disclosed to improve the stability of the cavity. The first assembly relates to a kinematic support for mounting an Invar bar. The second assembly defines a once-piece gimbal pivot ring designed to mount laser mirrors. The final aspect of the invention includes a mounting assembly designed to automatically compensate for changes in length of an Invar support bar due to temperature variations which could alter the cavity length of the laser.
