Measurements have been made of the change of the optical pathlength due tothermal transient effects of two laser rod materials: YAG:Nd and YAG:Nd, Lu. These optical distortion measurements were studied as a function of flashlamp input energy level, coolant temperature, and pulse repetition frequency. Experimental data were obtained by passing a collimated He-Ne probe beam through the flashlamp pumped laser rod and recording the detector output as a function of time. The data show a significant difference between YAG:Nd and Lu co-doped YAG:Nd with respect to thermal transient effects. Using existing theory, results of calculations that predict the thermal effects are also presented for comparison with the experimental observations.
已对两种激光棒材料YAG:Nd和YAG:Nd, Lu的热瞬态效应引起的光程长度变化进行了测量。这些光学畸变测量是作为闪光灯输入能量水平、冷却液温度和脉冲重复频率的函数进行研究的。通过使准直的氦氖探测光束穿过闪光灯泵浦的激光棒并记录探测器输出随时间的变化来获得实验数据。数据表明，在热瞬态效应方面，YAG:Nd和掺镥YAG:Nd之间存在显著差异。利用现有理论，还给出了预测热效应的计算结果，以便与实验观测结果进行比较。
