Paper Abstract

Here we investigate closed-loop adaptive optical system to compensate for laser beam aberrations. A bimorph mirror is used as a wavefront corrector and Shack-Hartmann wavefront sensor is an element for feedback control. Comparison of phase conjugation and multi-dither technique is shown.
