Abstract

We conduct a theoretical analysis of two models of transformation the spatial coherency transformation of the radiation propagating in the multi-mode waveguide. For each of them we obtain analytical relations connecting the number of spatially-coherent modes of the radiation appearing in the waveguide, parameters of the incoming radiation and the characteristics of the waveguide. We assess the efficiency of the radiation de correlation at various initial spatial statistics of the radiation and its quasi-nonstationary non-linear interaction with the waveguide's core. We find that the main factor limiting the de-correlation level of the light beams in the multi-mode waveguide with quartz core is the excitation of the Raman scattering. Raman scattering decreases the effective intensity of the radiation at the original frequency and the changes the dynamics of the phase-amplitude transformation of light.
