【摘要】 当调ＱＹＡＧ脉冲激光在ＬｉＩＯ３晶体中产生倍频时，由于部分基频光转换成倍频光，激光在倍频晶体中产生的光声信号将会增强，并随晶体的倍频位相失配角变化。报道了有关的实验结果，并进行了分析。更多还原

【Abstract】 When a Q switched YAG laser pulse radiation produces SHG in a LiIO 3 crystal, due to converting part of the fundamental radiation into the SHG radiation, the optoacoustic signals in the SHG crystal induced by the laser radiation will be enhanced, and vary with the SHG phase mismatching angle of the crystal. This paper reports experimental results and gives an analysis.更多还原
