Abstract

In this paper the efficiency of the heat sink for various configurations of the stacked-actuator wavefront correctors with thermostabilization of the mirror substrate through piezoactuators body was investigated. The simulation of the thermomechanical behavior of the mirrors under influence of the continuous-wave laser radiation with power of 10 kW was performed. Stacked-actuator deformable mirrors with diameters of 50, 78, 120 mm and 19, 55, 121 actuators, respectively, were used as wavefront correctors. Also, the alternative design of actuators with individual metal housing of control elements was proposed.
