摘要： A laser mirror is constructed to provide a reflecting surface having a minimum amount of distortion while it is reflecting a high-power high-quality laser beam. The mirror is constructed having a backing plate made of a vitreous ceramic which has a very low coefficient of thermal expansion and a stiffness comparable to many metals. The reflecting surface is formed on a heat exchanger plate means which is bonded to said vitreous ceramic and has a manifold on each end. A coolant is passed through said heat exchanger plate means to reduce internal thermal response. The heat exchanger plate means can be formed from two preformed metal plates or one metal plate with a second plate being formed by plating. The invention herein described was made in the course of or under a contract or subcontract thereunder with the Department of the Air Force.
