BRIEF COMMUNICATIONS: Interaction between a spatially modulated wave with a complex structure and a plane wave in a medium with nonlinear refraction
An analysis is made of the transmission of a monochromatic signal with a random spatial modulation through a nonlinear medium with a local response. It is shown that in the case of a weak nonlinearity the distortions of a partly modulated field are regular and can be used to determine the nonlinear refraction constant.
