Abstract

In this paper, the role of the vortex phase in the initial structure of wave field of the modified Bessel-Gaussian laser beam propagating in the atmosphere with weak turbulence, as well as in statistical regularities of beam wandering is studied by the semi-analytical method. The variance of the beam wandering depending on the diffraction conditions and the degree of turbulent distortions is determined. It is shown that the higher is the topological charge of the beam and its radial frequency, the smaller is the random wandering of the beam.
