Preprocessed high-power laser reflector

The invention discloses a preprocessed high-power laser reflector. The preprocessed high-power laser reflector consists of a preprocessed reflector, a radiator and an annular support frame. Firstly, according to calculation or an experiment, the thermal deformation of the reflector under laser irradiation is obtained, then the reflector is preprocessed, and finally the surface of the preprocessedreflector is coated and the reflector is assembled. The preprocessed reflector is maintained at a constant temperature through the radiator, and the thermal deformation caused by laser irradiation cancompensate preprocessing treatment, so that the preprocessed reflector is restored to have an ideal surface shape and the transmission quality of laser beams is ensured. The preprocessed high-power laser reflector provided by the invention is suitable for the field of high-power laser. 本发明公开了种预加工的高功率激光反射镜，它由预加工反射镜、散热器、环形支撑架组成。首先根据计算或实验得出反射镜在激光辐照下的热变形，然后对反射镜进行预加工处理，最后在预加工反射镜表面镀膜并组装。通过散热器将预加工反射镜维持在恒定的温度，激光辐照后引起的热变形可对预加工处理进行
