For some applications it is necessary to transform an intensity distribution from Gaussian to a flattop, doughnut, etc. It could be performed with the use of adaptive optics that distorts the phase of the beam and changes the shape of the focal spot in the far-field. In this paper, we present the flattop and doughnut beam formation result with the use of a bimorph and stacked-actuator deformable mirrors. The experimental results are also given.
