Abstract
A laser mirror having a cooled deformable reflecting surface is disclosed. The mirror's base includes a manifold for distributing coolant toward the mirror's faceplate and for receiving coolant which has circulated through the faceplate. The faceplate is comprised of a thin, deformable sheet of material which has a polished surface for reflecting laser radiation therefrom. The facesheet is supported above the base manifold by one or more actuators which may be selectively operated to selectively deform the mirror's reflecting surface. The faceplate includes one or more enclosed, elongated spaces which transverse substantially the entire width of the faceplate and through which coolant may be circulated to cool the faceplate. Coolant conducting members located around the periphery of the faceplate carry coolant between the faceplate and the base manifold to remove heat absorbed by the faceplate from the laser signal impinging on the mirror's reflecting surface.
