Paper Abstract

Simulation experiment of adaptive optics compensation to thermal blooming phase distortion induced by high energy laser propagation in the atmosphere are carried out. The results of spot pattern and Strehl ratio in the focal plane are obtained when the adaptive optics system is in the open or closed loop shape. The effect of adaptive optics compensation is prominent when the Bradley-Hermann distortion number ND is less than 300, and Strehl ratio is more than 0.4 on the whole. Phase compensation instability appears when the distortion number ND becomes greater than 300, in this case, the compensated beam Strehl ratio goes down rapidly. The experimental Strehl ratio without adaptive optics compensation agrees well with that of the thin lens approximation theory, while the one with adaptive optics compensation has some deviation with that of the ray-optics approximation theory.
