Abstract
The subject invention relates to a laser system where the length stability of the resonant cavity is important. Three unique mouning 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.
Claims9
A kinematic assembly for mounting a bar to a frame in a manner to stabilize the bar while isolating the bar from external forces on the frame that might tend to distort the bar comprising:
- first and second brace members mounted to said frame in spaced apart relationship, each said brace member having a bearing surface for supporting the bar while allowing limited longitudinal and rotational movement thereof;
- clamp member securely mounted to said bar adjacent the first brace member;
- and
- means for connecting the clamp member to said first brace member in a manner to constrain only the remaining longitudinal and rotational movement of the bar.
