Deformable mirror on the basis of piezoelectric actuators for the adaptive system of ISKRA-6 facility

Powerful laser systems of new generation are created nowadays - National Ignition Facility (NIF, USA), Laser Megajoule (LMJ, France) and ISKRA-6 (Russia). The most important problem after power characterization is formation of radiation of the necessary quality. For this purpose the use of adaptive optical systems (AOS) is provided in all three facilities. The present work is mainly devoted to characteristics definition and working off of the most problem AOS elements - wavefront sensor and wide-aperture deformable mirror for "ISKRA-6".
