摘要

Shenguang-III prototype is a multi-pass laser amplification system which includes a particular configuration of 4-pass amplifier. The beam rotates 90° and expands when it passes the 4-pass amplifier. A new scheme of adaptive optics for system aberration correction sets deformable mirror as cavity mirror of the 4-pass amplifier. This paper demonstrates this scheme and develops the mathematical relationship between deformable mirror and system aberration. Simulation and mathematic analysis indicate that the correcting capacity has relations with the beam expansion factor and the type of system aberration.
