本文研究了由反射镜和薄层非线性介质组成的谐振腔中光场周期性横向结构的形成。结果表明，当谐振腔长度是塔尔博特长度的一半的倍数时，存在周期性结构，该周期性结构在通过谐振腔的空部分和非线性介质的传播下自成像。估计了孔径损失的影响。这种谐振腔可用于二极管阵列泵浦的固体激光器。
The formation of a periodic transverse structure in the light field in a resonator consisting of mirrors and a thin layer of a nonlinear medium is considered. It is shown that, when the resonator length is a multiple of one half of the Talbot length, there exist periodic structures that are self-imaged under propagation through both the empty part of the resonator and the nonlinear medium. The influence of aperture losses is estimated. It is suggested that this type of a resonator may be useful for diode-array-pumped solid-state lasers.
