文摘We present a hybrid adaptive optics system for a k W-class solid-state slab master oscillator power amplifier laser that consists of both a low-order aberration corrector and a 59-actuator deformable mirror. In this system large defocus and astigmatism of the beam are first corrected by the low-order aberration corrector and then the remaining components are compensated by the deformable mirror. With this sequential procedure it is practical to correct the phase distortions of the beam（peak to valley up to 100 μm） and the beam quality β is successfully improved to 1.9 at full power.
