Abstract

Statistical characteristics of vortex beams propagating in the atmosphere are analyzed on the basis of numerical simulation. The probability density function of the intensity fluctuations are compared for common vortex beams and vortex beams synthesized by combining a fiber laser array. It is shown that the intensity fluctuations are lognormally distributed on the axis of a Gaussian beam when radiation is propagating through a turbulent atmosphere under weak fluctuations (the Rytov parameter is much lower than unity), while the probability density function of the intensity fluctuations at the axes of vortex beams is well approximated to the exponential distribution typical for strong fluctuations (the Rytov parameter is much higher than unity). This function is well approximated to a gamma distribution in the cases where the scintillation index is lower than unity independently of the beam type and observation point position relative to the propagation axis.
