Paper Abstract

This paper presents the novel optical closed-loop adaptive system (CLAS) 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 a continuous-surface deformable bimorph mirror. The control voltages applied to the electrodes reduce the wavefront distortions measured by a Shack-Hartmann wavefront sensor (SHWS). Adaptive system can correct the low-order aberrations with the frequency is about 25 Hz. The amplitude of corrected aberrations is about 10 microns and sensitivity is about 0.08 microns. The examples of the use of such systems to control for radiation of TW Ti:Sa lasers are presented.
