Abstract

We propose an optically efficient active beam-shaping system which consists of two continuous-surface deformable mirrors correcting for both phase and amplitude distortions to improve the beam quality of a laser. We present the results obtained with simulations and we validate next the technique using an experimental setup with two Boston micromachines MEMS deformable mirrors of 12 x 12 actuators each.
