Abstract

Intracavity phase distortions of radiation in the active medium of copper-vapor lasers are experimentally studied. By means of expansion of radiation wavefront deformations in Zernike polynomials, an analysis of aberrations spectrum contributing to the deformations is carried out. Device of phase-conjugated intracavity adaptive system designed to correct the deformations and technique of controlling the system are presented. The proposed technique avoids using computer-aided calculation of adaptive mirror control signals, which increases operation speed of the system and therefore correction precision.
