摘要：
Abstract—A wavefront corrector has been designed in the form of a cooled stacked-actuator deformable mirror for the correction of aberrations of laser radiation propagating through the turbulent atmosphere. The main parameters of this mirror are theoretically estimated. A technique for cooling the reflecting surface of the wavefront corrector through piezo actuators is suggested and experimentally tested. The main parameters of the deformable mirror are measured: the initial shape of the surface, the response functions of the actuators, the mirror stroke, and the frequency-amplitude characteristic of optical surface.
