摘　　要：用重复频率 1Hz、脉冲宽度 12 0 μs的闪光灯侧面抽运 ,在相同的实验条件下 ,对比了Nd∶KGW晶体与Nd∶YAG晶体的激光性能。在自由运转时 ,分别获得 1 0 %和 0 44 %的斜率效率和 0 5 4J、0 .76J的外推阈值能量 ,获得的最大输出能量为 384mJ和 16 5mJ。调Q运转时 ,Nd∶KGW激光器与Nd∶YAG激光器的斜率效率分别是0 16 %和 0 0 7% ,阈值能量为 5 9J和 12 5J。A comparative study of Nd∶KGW and Nd∶YAG laser crystals was conducted under the same experimental conditions in free-running mode and the Q-switched mode, which were pumped by flashlamp at a repetition rate of 1 Hz with a pulse duration of 120 μs. In free-running operation, the slope efficiencys and the extrapolated energy thresholds were determined to be 1.0%,0.44% and 0.54 J, 0.76 J for Nd∶KGW and Nd∶YAG rods, respectively. The slope efficiency of 0.16% and 0.07% for the Nd∶KGW and the Nd∶YAG were obtained in Q-switched mode with the extrapolated energy threshold of 5.9 J and 12.5 J, respectively.
