Nonlinear-optical methods for input field phase-distortion suppression and corresponding improvement of spatial coherence properties are presented. Analytical results obtained for different nonlinear two-dimensional feedback systems are verified by direct numerical simulation. Our experiments have demonstrated evidence of phase-distortion suppression.
