Abstract

In this paper we are presenting our latest results in the field of correction and formation high power pulsed laser radiation by means of adaptive optics. Our adaptive optical system consists of wavefront corrector (multy element bimorph mirror), control unit for such a mirror, PC and Shack-Hartmann wavefront sensor. The system is intended to compensate for slowly changing aberrations (frequency of corrected aberrations is about 5 Hz) with rather high amplitude (up to 20 μ). The efficiency of adaptive system was tested in various laboratories and institutes throughout the world on both femto second and high energy nano second lasers. It allowed to improve Strehl ratio up to 0.8.
