| 摘 要： | 采用300W准连续激光二极管阵列LDA端面泵浦Nd:YAG晶体,微柱透镜和透镜导管耦合,Cr4 :YAG可饱和吸收体被动调Q,实现调Q脉冲输出,激光腔长4.5cm,Cr4 :YAG晶体初始透过率Tcr=73.2%,泵浦能量63.48mJ,输出单脉冲激光,脉冲宽度10ns,单脉冲能量3.42mJ,输出脉冲被调制并产生明显尾脉冲现象,分析了原因,说明调制脉冲是由于空间电磁辐射干扰,Cr4 :YAG晶体的慢恢复可饱和吸收特性导致尾脉冲产生。

| Abstract: | A passively Q-switch QCW-300W LAD end-pumped Nd:YAG laser using Cr4 :YAG as a saturable absorber is reported.Coupling system of the laser are micro-cylindrical lens array and lens duct,which are made by us.The Q-switch laser lenth is 4.5cm,using a 73.2% initial transmmion Cr4 :YAG crystal.At a pumped power 63.48mJ,the laser produces one Q-switching pulse,a Q-switch pulse width 10ns and a single pulse energy is 3.42mJ.In the Q-switch experiment,the Q-switch pulse is brewaged and end-pulse is growed.This phenomena and the experiment results were analyzed and discussed. |
