The eigenvalues for all the significant low-order resonant modes of an unstable optical resonator with circular mirrors are computed using an eigenvalue method called the Prony method. A general equivalence relation is also given, by means of which one can obtain the design parameters for a single-ended unstable resonator of the type usually employed in practical lasers, from the calculated or tabulated values for an equivalent symmetric or double-ended unstable resonator.
使用一种称为 Prony 方法的特征值方法，计算具有圆形反射镜的不稳定光学谐振器的所有重要低阶谐振模式的特征值。还给出了一个一般的等效关系，通过该关系，可以从等效对称或双端不稳定谐振器的计算值或表格值中，获得实际激光器中通常使用的单端不稳定谐振器的设计参数。
