Paper Abstract

This paper presents adaptive optical closed loop system with bimorph mirror as a wavefront corrector and Shack-Hartmann wavefront sensor to compensate for the aberrations of the high power lasers. Adaptive system can correct for the low-order aberrations in the real-time -- the frequency of corrected aberrations is less than 25 (30) Hz. The amplitude of such aberrations -- about 7 microns. These parameters are mostly determined by utilized Shack-Hartmann wavefront sensor. Number of corrected aberrations -- up to 30th Zernike polynomial (excluding tip-tilt). We are presenting the results of the use of our adaptive system in several high-power laser systems such as ATLAS, LULI, JAERI and Beijing Institute of Physics.
