Paper Abstract

Based on numerical solution of the parabolic wave equation for the complex spectral amplitude of the wave field by method of splitting into physical factors the propagation of the superposition of broadband pulsed laser Laguerre- Gaussian beams in a turbulent atmosphere has been studied. It has been found that the difference in the energy density fluctuations of the axial superposition of several modes and one mode, the value of which is determined by the sum of the topological charge magnitudes, of pulsed Laguerre-Gaussian beams at the same turbulent conditions on the propagation path within the statistical error is the same.
