在本文中，我们报告的数值和实验结果的基频激光通过二次谐波产生过程中，通过引入相位失配因子的峰值强度稳定。在相位失配温度为146.7 ℃下加热的I型非临界相位失配三硼酸锂晶体，使1064 nm纳秒级基频激光的峰值强度起伏从7.0%减小到1.1%。该方法适用于平顶光束轮廓激光器的功率稳定。
In this paper, we report on numerical and experimental results for the peak intensity stabilization of a fundamental laser through the second-harmonic generation process by introducing a phase-mismatching factor. The peak intensity fluctuation of a nanosecond-order fundamental laser at 1064 nm is reduced from 7.0 to 1.1% with a type-I noncritical phase-mismatching lithium triborate crystal heated at a phase-mismatching temperature of 146.7 C. The method is applicable to the power stabilization of the laser with a flat-top beam profile.
