| 摘 要： | 基于传输矩阵理论,针对端面抽运的U型腔Nd∶YVO4固体激光器谐振腔的稳定性进行了理论分析和数值模拟。通过改变“U”型腔各个臂长得到不同腔臂长条件下谐振腔的稳区范围和晶体中心处的振荡光斑，比较稳区范围以及振荡光斑，找出一组腔参数值使谐振腔能够在较高泵浦功率下保持稳定且振荡光斑足够理想。按照确定的腔参数值进行了具体实验，实验结果表明:按选定参数设计的谐振腔在调Q重复频率为100kHz，泵浦功率为60W时，激光器能够稳定工作并输出21.6W的高重频激光，谐振腔稳区范围的变化规律与理论计算基本吻合。 |

| Abstract: | According to the transmission matrix theory, the resonator stability of end-pumped U-folded cavity Nd∶YVO4 solid-state laser was theoretical analyzed and numerically simulated. The stable region range of different cavity arm length and the oscillation spot at the center of crystal were obtained by changing several arm length of ″U″ cavity resonator and making comparison. A group of cavity parameters were obtained, which could keep the cavity steady at the high pump power and make oscillation spot perfect. Experiment was conducted with a group of cavity parameters. The experiment result shows that, resonator cavity work steadily and 21.6W output power is obtained under 100kHz repetition frequency and 60W pumped power. The results agree with the theoretical analysis. |
