Abstract
The question of stability of the vortex Bessel beams formed in turbulent atmosphere is theoretically considered. In the given research, characteristics of spatial structure of distribution of mean intensity of vortex Bessel beams in an inhomogeneous medium are analyzed in detail. The quantitative criterion of possibility of formation of vortex Bessel beams in turbulent atmosphere is derived. On the basis of the analysis of behavior of several physical parameters of mean intensity of optical radiation it is shown that the stability of the form of a vortex Bessel beam during propagation in turbulent atmosphere increases with an increase of the value of a topological charge of this beam.
