Аннотация: As applied to solving the problem of phaseconjugation of light beams, the spatial speckle structure of thedegree of spatial coherence of dispersed laser beams withdifferent spectral widths is numerically investigated, and thecharacteristic sizes of speckles in the longitudinal direction aredetermined. The distributions under consideration wereanalyzed using both traditional statistical methods and theformalism of wavelet transforms. It has been established thatthe transformation of the speckle structure and the increase inthe size of speckles with distance from the initial plane occur thefaster, the wider the radiation spectrum. The results obtainedcan be used to optimize the characteristics of devices for phaseconjugation
