Temporal studies of depolarization loss in a thermally strained, pulsed, Nd:glass laser system are reported. The probe beam consisted of a 70-mJ-20-ns, TEM(00), Nd:glass laser oscillator pulse. It was observed that, in all the cases of input pump energy density ø, the peak of the profile of depolarization loss is separated from the peak of population inversion by approximately 150 micros. The peak values of gain and depolarization loss showed a dependence of ø(5/3) and ø(2), respectively. Theoretical prediction of saturation of depolarization loss, at high input pump energy density, was found to be in agreement with the experimental observation.
报道了在热应变、脉冲钕玻璃激光系统中去极化损耗的时间研究。探测光束由一个70 mJ - 20 ns、TEM(00)模式的钕玻璃激光振荡器脉冲组成。据观察，在所有输入泵浦能量密度ø的情况下，去极化损耗曲线的峰值与粒子数反转峰值相隔约150微秒。增益和去极化损耗的峰值分别显示出对ø(5/3)和ø(2)的依赖性。发现在高输入泵浦能量密度下去极化损耗饱和的理论预测与实验观察结果一致。
