ABSTRACT:
The reflective mirror face plate of a deformable adaptable mirror for laser ystems is cooled by an improved heat exchange apparatus. In accordance with the invention jets of cooling fluid impinge normal to the face plate in addition to coolant flowing parallel to the surface of the face plate. Coolant manifolding is provided within the mirror allowing the coolant to flow through a nozzle plate and thereafter impinge and spread over a knurled back surface of the reflective plate. Electromagnetic actuators act on control rods to transmit forces to the face plate thus controlling its curvature to produce optimum laser beam reflection.
