Abstract :
Transformation of vortex Bessel beams during propagation in turbulent atmosphere was theoretically analyzed. Deforming influence of the randomly inhomogeneous of the turbulent medium on formation of diffraction-free beams leads to disappearance of their invariant properties. In the given research features of evolution of spatial structure of distribution of mean intensity of vortex Bessel beams in turbulent atmosphere are analyzed. With use of cognitive graphs of mean intensity of optical radiation it is visually shown, that stability of the form of a vortex Bessel beam during propagation to turbulent atmosphere increases with rise of value of a topological charge of this beam.
