电光调Q脉冲串Nd∶YAG激光器研究
Study on multi-pulse of high power electro-optical Q-switched Nd∶YAG laser
摘要
设计了一台高能量输出的电光调Ｑ脉冲串Nd∶YAG激光器, 可以对脉冲串重复频率、脉冲数目、脉冲间隔进行调节。重复频率1～10Hz, 每一个脉冲串含有1～3个脉, 其间隔大于200μs可调。采用平凸腔的结构, 对一定重频下的热透镜效应进行补偿。典型的实验结果为：当重频为10Hz、脉冲间隔为548μs时, 三脉冲最大输出能量608mJ, 双脉冲最大能量输出405mJ, 单脉冲最大输出能量为200mJ, 其中单个脉冲的脉宽约为8ns, 发散角为3.4mrad。
Abstract
A electric-optical Q-switch pulse-array Nd∶YAG laser output with high energy is obtained. Timing of the pulse, pulse repetition, pulse number, pulse interval time can be adjusted. Repetition frequency 1~10Hz can be regulated. There are three pulse every multi-pulse, and the interval is greater than 200μs. The typical results, the maximum energy of the multi-pulse is up to 608 mJ, the double-pulse is 405mJ and the single-pulse is 200mJ when the interval of the pulse is 548μs. The single pulse width is 8ns and the divergence is 3.4mrad.
