摘要
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 influence of curvature radius of the cavity mirrors on the performance of high power single frequency laser is investigated. When the cavity length is kept constant, both the pump power at the optimal operation point and the maximum output power decrease with the increase of curvature radius of the cavity mirrors beside the gain medium. However, if the cavity length is shorten to a certain extent, the pump power at the optimal operation point and the maximun output power can be recovered. The experimental results are consistent with the theoretical expectation.
