摘要
为了对激光谐振腔体进行优化设计,采用ABCD光学传输矩阵理论,计算得到具有普适性的三镜折叠腔内高斯模式束腰的解析解.对一典型平平热透镜腔进行计算分析,结果表明:在针对其进行优化设计的泵浦范围内,腔体稳定性很好,激光光斑半径基本不随泵浦功率变化而波动.实验中以808nm尾纤输出的激光二极管端面泵浦Nd:YAG晶体产生连续1064nm激光,激光输出结果与理论模型值能够较好地相符.
According to ABCD transmission matrix theory,analytical solutions concerning Gaussian beam were derived in a V-configuration folded cavity.The calculated results for the thermal lensing effects of laser crystal in a plano-plano cavity indicate that such a resonator operates rather stably in the pumping power range of interest,and that the laser radius varies insignificantly with pumping power in the stable region.Experiment on 808 nm LD end-pumped cw 1 064 nm Nd:YAG laser was performed.The experimental results are in agreement with the theoretical analyses.
