Paper Abstract

In this paper, we report in detail the adaptive optical closed loop system with bimorph deformable mirror as a wavefront corrector and Hartmann-Shack wavefront sensor to compensate the aberrations of the laser beam in the 23TW chirped-pulse amplified Ti:sapphire femtosecond laser system in Shanghai Institute of Optics and Fine Mechanics, CAS. The adaptive system is placed in the vacuum chamber behind the compressor. After the adaptive compensation for the laser beam, we can get the nearly diffraction limited beam.
