Abstract

This paper discusses the novel adaptive optical closed ioop system with bimorph mirror as a wavefront corrector and Shack- Hartmann wavefront sensor to compensate for the aberrations of the laser beam occurred during the distribution of the beam from laser to processed material. Adaptive system can correct for the low-order aberrations in the real-time —the frequency of corrected aberrations is less then 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 15th Zernike polynomial (excluding tip-tilt).
