| 摘 要： | 为消除强激光微沟道水冷镜冷却水压力和扰动对激光输出稳定性的影响和冷却水道对冷却水流量的限制,提出并设计了热管冷却镜。采用ANSYS有限元软件，模拟计算了相同结构下镜面热吸收为12 W/cm2，实心镜、微沟道水冷镜与热管冷却镜连续工作60 s下镜体温升和镜面变形量。计算结果表明：热管冷却镜镜面轴向位移最大峰谷值为0.109 4 μm，微沟道水冷镜最大峰谷值为0.845 μm，实心镜镜面最大峰谷值为1.33 μm,热管冷却镜对镜面变形改善显著。

| Abstract: | Mirror surface reflecting high power laser would be deformed by the pressure of the coolant in a liquid cooling mirror system. In order to eliminate the impact of pressure and vibration of cooling water of micro channel mirror on the stability of the output beam and the space limitation of micro channel to flow of water, an outside cooling mirror with heatpipe was designed. In the same conditions, solid mirror, micro channel water cooled mirror and heatpipe outside cooling mirror are simulated by ANSYS program. The time-varying thermal deformation of the mirrors under heat absorption of 12 W/cm2 and continuous work of 60 s is obtained. The results indicate that the maximal mirror surface deformation of z-axis between peak and valley of solid mirror, micro channel water cooled mirror and h |
