摘要

针对中红外固体激光器结构紧凑、抽运源模块温度要求严苛等引起的激光器散热难题，采用强制对流冷却、半导体制冷与热管导热等多种方法相结合建立了激光器的散热系统。应用COMSOL有限元软件建立了紧凑型中红外固体激光器散热系统有限元模型，利用温度传感器采集激光器侧壁和内部温度数据，对比有限元计算结果验证了模型的有效性。基于此模型计算了在不同环境温度条件下如风扇转速、热管等参数对激光器散热结果的影响，提高风扇转速、增加热管等方式可提高激光器散热效果，并且随着环境温度升高，散热效果改善明显。

Abstract

Cooling compact mid-infrared solid state laser is difficult for its compact structure and temperature restriction of laser pump module. A laser cooling system is proposed using forced convection cooling technique, thermo electric cooling technique and heat pipe technique. A finite element model for the laser cooling system is built with the COMSOL software. Temperature data is experimentally measured by sensors. The validity of this model is verified with the experimentally measured data. The effect of cooling system parameters, such as fan speed and heat pipe, on temperature distribution is numerically computed with the finite element model at different environmental temperatures. The results indicate that increasing the fan speed and installing the heat pipe are beneficial to improving the cooling effect, and the cooling effect is more obvious with the increase of environment temperature.
