研究了高功率单频激光器中增益晶体所在分臂腔镜的曲率半径对激光器工作状态的影响。当增益晶体所在分臂腔镜的曲率半径增大时,如果腔长不变,则激光器最佳工作点对应的抽运功率和最大输出功率均降低;而适当调整腔长,又可以恢复激光器最佳工作点对应的抽运功率和最大输出功率。在自制的高功率单频激光器上进行验证,实验结果和理论预期比较吻合。
The effect of the radius of curvature of the splitter cavity where the gain crystal is located on the working state of the laser is studied. When the radius of curvature of the lumen mirror where the gain crystal is located increases, if the cavity length is constant, the pump power and the maximum output power corresponding to the optimum operating point of the laser are both reduced. When the cavity length is adjusted properly, Good work point corresponding to the pumping power and maximum output power. The self-made high-power single-frequency laser is verified, the experimental results are in good agreement with the theoretical expectation.
