Paper Abstract

Nonlinear self-action of light fields in a layer of cubic nonlinear medium can serve as a convenient tool for controllable coherence manipulation. In the present work this scheme is considered for partially coherent input light. Due to experimental requirements, we consider the model of multimode laser. For the purely phase statistics of the input beam (when the average intensity can be represented in factorized form I(r,t) equals I(r)I(t)), it is possible to find out rather simply the dependence of the effective number of (coherent) modes in output radiation on the input number of modes and the nonlinearity parameter.
