Paper Abstract

There has been offered a method oftransformation of spatial coherency of pulse laser radiation based on the phase self-modulation in multi-mode waveguide. We have conducted analysis of the peculiarities of the transfer of correlation properties of the radiation in gradient waveguide with regular and non-regular core's refraction index profile distribution. We have also conducted a comparative analysis of the global coherency degree parameter of the radiation at the end of non-homogeneous waveguide and non-waveguide media. We show that the most effective mechanism of decorrelation of pulse radiation in the waveguide is the fluctuations of radiation phase scattered on the heterogeneousness of the waveguide's core refraction index; the fluctuations being induced at non-linear interaction of the radiation with spatially non-uniform intensity distribution.
