A laser beam cleanup system based on a 37-element bimorph deformable mirror (DM) is presented, to correct the wavefront aberrations of slab laser amplifier and improve the output laser beam quality. The strip-shaped laser beam is expanded by a cylinder mirrors expander to match with the bimorph DM. The stochastic parallel gradient descent (SPGD) algorithm is utilized to optimize the surface of bimorph DM. The normalized power in the bucket (NPIB) of laser beam is enhanced by 2-3 times, after the wave-front aberrations are corrected.
