Based on the theoretical and experimental results of adaptive optics system application in SG-Ⅲ prototype facility, the main scientific and technical problems were researched and solved, the efficiency was verified by experiment. In order to fulfill need of future high power solid-state laser driver wavefront correction, the scheme of combined adaptive optics system with continuous phase plate (CPP) was researched in theory. “One big deformable mirror (DM) with one CPP ”and “One small DM with two CPPs” schemes were analyzed by numerical modeling. The result showed that the latter scheme can achieve the goal of controlling the entire beam wavefront, and fulfill the need of focal spot size and uniformity for physics experiment. The results can also provide theoretical reference to design wavefront correction system in high power solid-state laser facility.
