Abstract

Sometimes to improve the performance of industrial or scientific laser technology it is desired to transform an intensity distribution from Gaussian to the flattop. The adjusting of the intensity profile can be implemented by means of adaptive optics. In this paper we present laser beam control with bimorph deformable mirrors. Shack-Hartmann wavefront sensor is used to determine the control signal for the bimorph deformable mirror while focal spot is observed with CCD camera to check the result of beam shaping.
