摘要：

This paper presents an adaptive optical system intended for focusing, the radiation of powerful processing lasers. The system consists of a wave-front corrector, a wave-front meter, and a software-hard ware system for controlling the corrector. A flexible bimorph mirror is used as a corrector. An M-2 sensor is used to analyze the radiation-focusing quality, making it possible to estimate such parameters of the laser radiation as the diameter, the divergence angle, and the quality parameter M-2. The bimorph mirror is controlled by means of a combined method, based on gradient methods of searching for the extremum and a genetic algorithm. The system makes it possible to correct low-order aberrations and to estimate the focusing efficiency of the laser radiation. (c) 2007 Optical Society of America.
