Numerical Simulation of the High-order Gaussian Laser Beam Cleanup System Based on Optimization-translation Adaptive Optics

摘要

We present research on high-order Gaussian laser beam cleanup by using adaptive optics (AO) technique. A 64-element adaptive optics beam cleanup simulation system based on Stochastic Parallel-Gradient-Descent (SPGD) Algorithm was set up. The far-filed energy centrality of TEM_(10) mode was advanced and the evaluation function increased more than a factor of 4.6 when the system evolves from open-loop into close-loop state. The experiments results indicate the feasibility of Adaptive Optics in mode transform system.
