摘　　要：从理论和实验上讨论了水冷铜镜变形的规律，从而设计出多种多层镜，其中回流式多层镜在０．１３ＭＰａ通水压力下净吸收８６．９Ｗ激光功率时，总变形仅０．１０μｍ，约为同等条件下普通水冷铜镜变形量的１／４０。The theme discuss distortion of active cooling copper mirror theoretically and experimantally. Thereby, a serious multilayer mirrors are designed. Among those, a mutilayer mirror with circular coolant channel is better. Its total distortion only 0.10μm, when the pressure of coolant is 0.13MPa, the absorbed laser power is 86.9W. It is about 1/40 of the distortion of the traditional active cooling mirror under the same conditions.
