| 摘 要： | 计算出固体棒状热容激光器在不同散热边界条件下的温度分布和随时间的演变，与实验测量的结果进行了对比。计算结果表明：激光器工作在热容模式时，不同散热边界条件下激光介质内的温度分布在激光发射期间区别不大，激光发射期间，激光介质内的温度分布主要取决于泵浦光的吸收。但是散热过程中的不同散热边界条件下温度分布演化大不相同，此时的温度分布主要取决于散热边界条件。

| Abstract: | In this paper,contour plots comparing measured and calculated temperature profiles are presented.The results suggest numerical calculations accord with the measurements for dynamic temperature profiles in heat-capacity laser rods.During lasing process,the cooling condition almost doesn't influence the dynamic temperature profiles in the active medium.The dynamic temperature profiles in the active medium are dependent on the pump absorption.However,the dynamic temperature profiles in the active medium with different cooling conditions are distinct during the cooling process. |
