Abstract

Statistical characteristics of the vortex laser beams propagating in the turbulent atmosphere are analyzed. The vortex beams are appeared to be less affected by turbulence as compared with the conventional beams: for the vortex beam the variance of random displacements and the variance for fluctuations of the orbital angular momentum, which are induced by atmospheric turbulence less than these characteristics for the vortexless beam, beams having a larger topological charge are founded to be more stable.
