Abstract

A bimorph deformable mirror with a diameter of 320 mm, including 127 control electrodes, has been developed and investigated. The flatness of the initial surface of the mirror RMS = 0.16 μm was achieved due to mechanical adjustment in the system of fixing the mirror substrate in the frame. An adaptive system with deformable mirrors and a ShackHartmann-type wavefront sensor was installed in a 4.2 PW Ti: Sa laser. Correction of the wavefront made it possible to obtain a record radiation intensity in the focusing plane of 1.1x10²³ W/cm², while the Strehl ratio was 0.84.
