摘要：
We present the operator model of the laser resonator with an active output mirror based on the Fabry - Perot interferometer with nonflat (spherical and aspherical) mirrors and an adjustable gap. The results of numerical simulation of a microchip laser with a thermal lens and an active output interferometer-based mirror are given. It is shown that the use of an active interferometer as the output cavity mirror allows one to control the number of transverse modes of laser radiation and its power; in this case, the beam divergence can be reduced by a factor of 1.5-2.5.
