Abstract
An improved cooled high power laser mirror system is described which uses a ilicon mirror face with an attached silicon nitride based heat exchanger assembly. The silicon nitride provides a high strength, high toughness, and stiff backup assembly. The particular silicon nitride system is microstructurally engineered to provide a thermal expansion match to silicon designed to insure high quality bonding and minimum mirror distortion.
