Liquid or gas cooled flexible beam-compensating adjustable cylindrical mirror

摘要

A liquid or gas cooled adjustable cylindrical mirror (10) for a high powered laser includes a plurality of parallel cooling conduits (20-32) which abut the back surface of the mirror in order to effect heat transfer. The cooling conduits (20-32) are vertically adjustable, and by virtue of their abutting relationship with the flexible mirror are operative to control the curvature of the mirror. A housing (16) for the mirror (10) is provided with a pair of pressure blocks (50) which secure the mirror in position and serve to direct stray photons into the usable area of the reflected beam.
