SEVERAL KEY MANUFACTURE TECHNOLOGIES OF MIRROR IN HIGH POWER LASER SYSTEM

The thermal capability of material, the surface defect and the fabrication techniques of the mirrors using in high power contiune laser are analyzed in this paper. Several features for manufacturing mirror must be considered, which are the ratio S of the thermal capability, microstructure, size of the surface defect, the crystal direction on the mirror material and design of technic for the mirror. Moreover the results of experimentation are given．
