Abstract
This paper presents the novel adaptive optical closed loop system (ACLS) for compensation of the laser beam aberrations and results of its application in high power lasers. A closed-loop adaptive algorithm is developed to control for deformable bimorph mirror. The control voltages applied to all electrodes reduce the wavefront variations measured by a Hartmann-Shack wavefront sensor (SHWS). Adaptive system can correct for the low-order aberrations in the real-time - the frequency of corrected aberrations is 25 (30) Hz. The amplitude of such aberrations - about 7 microns. It is shown also the successful application of the developed ACLS for correction of aberration of different kinds of lasers.
