High efficiency LD side-pumped green laser
摘要
根据ABCD传输矩阵理论，对激光二极管侧泵的Nd∶YAG/KTP腔内倍频固体激光器Z型谐振腔进行了理论分析，采用Matlab对腔参数进行了理论计算。通过理论计算，选择适当腔参数进行了实验研究，当重复频率为9 kHz，输入电功率302.5 W时，获得了17.27 W绿光输出，输出不稳定性小于0.9%，电光转化效率为5.7%，光束质量因子M2x=3.351, M2y=3.759，发散角为0.68 mrad。
Abstract
According to ABCD transmission matrix theory, A Z-type resonator used for laser diode (LD) side-pumped intracavity frequency-doubled Nd:YAG /KTP laser was analyzed and calculated by software Matlab. We selected a set of proper cavity parameters, at 9kHz repetition frequency and 302.5W input electrical power, a 17.27W green laser was obtained with an electrical-optical conversion efficiency of 5.7% and divergence angle of 0.68mrad, the beam quality was M2x=3.351, M2y=3.759，output instability was less than 0.9%.
