Paper Abstract

As for master-oscillator-power-amplifier (MOPA) laser systems, Aberrations generated by thermal effects, the mirrors surface and optical elements play important roles to deteriorate laser beam quality. To obtain good beam performance, a compact adaptive optics (AO) system for a Nd:YAG zigzag slab amplifier is built. A rectangular tilt mirror (DM) and a 39-element rectangular piezoelectric deformable mirror in combination with a stochastic parallel gradient descent (SPGD) algorithm is introduced for aberrations correction. Experimental results demonstrate that the output beam quality can enhanced greatly at different power level when the AO system is in operation.
