| 摘 要： | 采用侧面泵浦Nd∶GdVO4晶体的方式，利用I类相位匹配LBO（LiB3O5）晶体进行腔内倍频。腔型采用平凹直腔，利用软件模拟优化谐振腔腔镜曲率半径、腔长以及晶体放置位置等参数，在最大注入电功率750 W时获得9.7 W的671 nm光输出，重复频率10 kHz，发散角7.9 mrad，电-光转换效率约为1.3%。

| Abstract: | By using the side-pumped Nd∶GdVO4 crystal and type-I critically phase-matched LiB3O5 (LBO) crystal in cavity, the red light at 671nm was obtained. The cavity type of plane-concave was used to avoid decreasing the efficiency of doubling frequency caused by astigmatism. The parameters such as the resonant cavity curvature radius, length and laying position of crystal were optimized by software. The 671 nm red light of 9.7 W was obtained with injected electric power of 750 W. The repetition rate was 10 kHz, the angle of divergence was 7.9 mrad, and the electric-optical conversion efficiency was about 1.3%. |
