Composite laser mirror

摘要

A laser mirror is described having a base section, a backing section, and a laser radiation reflecting surface. The base section and backing section are formed of graphite fiber reinforced glass. The fibers in the base section are oriented in a plane parallel to the laser radiation reflecting surface. The fibers in the backing section are oriented in a plane perpendicular to the radii of the reflecting surface. Based on the materials employed and the orientation of the fibers, a laser mirror with improved thermal distortion properties results.
