稳定的谐振器结合了适当调整的望远镜，可以使大容量 TEM00 模式的 Nd:YAG 激光器可靠运行。选择望远镜调整是为了最大限度地减少激光棒焦距变化的影响，同时确保共焦谐振器的最佳模式选择特性。应用于射线传输矩阵的简单近似允许对谐振器进行详细分析。该分析产生了与模式光斑尺寸、谐振器长度、望远镜放大倍率和散焦以及衍射损耗相关的简单设计方程。实验结果与该分析结果非常吻合。
A stable resonator incorporating a suitably adjusted telescope gives reliable operation of an Nd:YAG laser with a large-volume TEM00 mode. The telescope adjustment is chosen to minimize the effect of focal length variations in the laser rod and at the same time ensures the optimum mode-selection properties of a confocal resonator. Simple approximations applied to the ray transfer matrices allow a detailed analysis of the resonator to be performed. This analysis yields simple design equations relating the mode spot sizes, resonator length, telescope magnification and defocusing, and diffraction losses. Experimental results show excellent agreement with the results of this analysis.
