ANALYSIS OF THE THERMO-STRESSED STATE OF AN UNCOOLED DEFORMABLE LASER MIRROR

Analytical and fi nite-diff erence methods have been used to analyze the thermo-stressed state of an uncooled deformable mirror. Assessments have been made of temperatures and movements of the optical surface of the mirror both in assigning a uniform intensity of the heat fl ux and in the presence of global and local nonuniformities. A conclusion has been drawn about the possibility of using simplifi ed analytical computational methods in design analysis
