摘要
激光器运行中,腔镜的变形造成激光输出功率下降和光束质量变坏,大大制约了高功率激光器性能的提高。通过对激光器腔镜吸热产生的热变形及冷却流体对镜片压力变形分析,提出了热管冷却腔镜的方法,介绍了热管冷却原理和热管在导热方面的优点,设计了热管冷却腔镜方案,为有效控制强激光系统中镜片表面变形提供了有效途径。
Abstract
The cavity deformation can lead to the decline in the laser output power and the beam quality deterioration when the laser operates, so the performance enhancement of the high power laser is restricted greatly. The heat deformation based on the heat absorption of the laser cavity and the lens pressure deformation based on cooling fluid are analyzed, the method of the heat pipe cooling cavity mirror is proposed. The principle of the heat pipe cooling and the advantage of heat pipe in heat conductivity are introduced, the solution of heat pipe cooling cavity mirror is designed, which provides the effective way to effectively control the lens surface deformation of the high power laser system.
