Research of laser reflectors cooled by a thermoelectric refrigerator

The surface distortion of reflector in the laser cavity caused by high laser power makes the mirror surface deviate from the design requirements. The experiments show that both the copper reflector and the silicon reflector cooled by thermoelectric refrigeration can compensate the distortion caused by laser power, so that the reflector surface is unchanged when it works. The laser reflectors cooled by thermoelectric refrigeration has the advantages of no pressure distortion,the refrigerating power can be easily controlled and the cooling is even.
