Abstract

Based on numerical simulation, the broadening of the Laguerre-Gaussian beams propagating in the turbulent atmosphere is analyzed. Mean intensity profiles are compared for the Laguerre-Gaussian and doughnut hole beams, which differ only in the presence or absence of the vortex phase component in the initial field distribution. It is shown that as the topological charge of the Laguerre-Gaussian beam in the turbulent atmosphere increases, the effective beam size increases due to turbulence.
