Abstract
The coherent properties of the higher modes of the Bessel optical beams formed in the turbulent atmosphere are studied. The degree of coherence of vortex Bessel optical beams depending on parameters of a beam and characteristics of the turbulent atmosphere are considered. It is shown that, at low levels of fluctuations in the turbulent atmosphere, the degree of coherence of a vortex Bessel optical beam essentially depends on value of a topological charge of a beam. At high levels of fluctuations in the turbulent atmosphere, the degree of coherence of a vortex Bessel beam becomes closer to the similar characteristic of a spherical wave at much higher levels of fluctuations, than it was observed for a fundamental Bessel beam.
