Paper Abstract

An adaptive beam intensity shaping method based on the combination of a 61-element deformable mirror and stochastic parallel gradient descent algorithm is presented. This technique can adaptively adjust the voltages of 61 actuators on the deformable mirror to reduce the difference between target beam shape and actual beam shape. Numerical simulations results show that within the stroke range of the deformable mirror, the system can be well used to create Gaussian and super-Gaussian beam profiles on the focal plane that closely match the desired target parameters.
