Paper Abstract

The vortex beams LG0L broadening has been investigated by numerical simulation of propagation through atmospheric turbulence. The focused and collimated beams were considered. The split-step Fourier method was used for solving scalar wave equation for a randomly inhomogeneous medium with a power-law Kolmogorov spectrum. The average intesity of collimated and focused Gaussian and vortex beams has been compared. The effective sizes are found to be broadened less than the Gaussian beam while propagated through the same medium. The higher the topological charge’s value /l/, the less the beam broadening is observed.
