Abstract
In this paper, we detail the new scheme that precompensates 30-fs, 10-TW laser beam aberrations in order to get the best laser focal spot on target. The adaptive optics loop consists of two four-wave lateral shearing interferometer as the wave front sensor. Wave front correction is achieved dielectric coated bimorph deformable mirror.
