摘要

针对热容运转模式下的固体激光器，对二极管泵浦光强分布进行修正，并且考虑激光介质比热容和热传导率随温度变化的特性，建立了三角均布脉冲LD侧面泵浦固体激光介质的热传导物理模型。利用有限元方法，对激光介质的温度变化过程进行了模拟与分析，并且，与连续泵浦、脉冲泵浦模式下的热稳态固体激光介质的热效应分布进行了对比讨论。讨论结果对热容激光器的设计工作提供参考。

Abstract

according to the diode pumped light intensity distribution and property of YAG materials that varies with temperature

stimulated and analyzed the change process of temperature in laser crystal media with heat capacity mode using finite element method. In order to achieve this

a side-pumping geometry with a triangle uniform distribution was adopted and its thermal conduction model of laser crystal was established. Furthermore

the different thermal effect was discussed contrastively under condition of heat capacity

continuous pumping and pulsed pumping operations. Results show that this work is useful to the experiment of the heat capacity lasers.
