| 摘 要： | 对闪光灯泵浦Cr,Tm,Ho:YAG平平腔激光器进行了实验研究。在5Hz室温运行下，获得最大能量为217mJ的脉冲输出，其斜效率约为1.2％。利用有限元方法计算了晶体内温度的分布，分析了晶体内温度对激光阈值和斜效率的影响。模拟了光在腔内的分布，计算热晶体的焦距和晶体内光斑的大小，讨论了晶体热效应对激光输出的影响。

| Abstract: | The characteristic of flash pumped Cr,Tm,Ho:YAG laser with plane-plane cavity are reported. At room temperature with frequency 5Hz, the maximum output pulse energy is 217mJ and the slope efficiency is 1.2%. The temperature distribution of laser crystal is calculated by finite element method and the influence of crystal temperature to laser pump threshold and slope efficiency is analyzed based on the experiment results. By using the laser matrix theory, the thermal focus length and the laser radius are given and the thermal effect of laser crystal to laser output is discussed. |
