谐振器包含一个聚焦棒进行了彻底的分析。结果表明，作为杆的屈光力的函数，存在两个相同宽度的稳定区，并且杆中的模体积总是呈现一个静止点。在这一点上，输出功率对焦距波动不敏感，并且杆内的模式体积与谐振器稳定的输入功率的范围成反比。这两个区域在失准灵敏度方面明显不同，一般来说，一个区域的失准灵敏度比另一个区域的失准灵敏度大得多。本文提出了两种大模体积、对焦距波动和失调敏感度低的单模固体激光谐振腔的设计方法。
Resonators containing a focusing rod are thoroughly analyzed. It is shown that, as a function of the dioptric power of the rod, two stability zones of the same width exist and that the mode volume in the rod always presents a stationary point. At this point, the output power is insensitive to the focal length fluctuations, and the mode volume inside the rod is inversely proportional to the range of the input power for which the resonator is stable. The two zones are markedly different with respect to misalignment sensitivity, which is, in general, much greater in one zone than in the other. Two design procedures are presented for monomode solid-state laser resonators with large mode volume and low sensitivity both to focal length fluctuations and to misalignment.
