Abstract
A partially coherent laser beam propagated in the far region of diffraction through a nonlinear layer adjacent to the radiation plane is considered. The propagation is described using a small-angle approximation of a transfer equation. It is demonstrated that 'slow' phase correction is effective only in the limited region of the beam energy parameters. Beyond the limits of the region even the optimum phase correction does not decrease angular expansion, and the use of nonoptimum algorithms causes deterioration of radiation characteristics. 'Fast' phase correction makes it possible to derive the angular expansion value that is less than the diffractive value, when a 'focusing lens' formed in a nonlinear layer.
