Propagation of Gauss?Bessel beams in turbulent atmosphere

This paper studies the propagation properties of Gauss–Bessel beams in a turbulent atmosphere. Based on the extended Huygens–Fresnel principle, it derives the intensity distribution expression for such beams propagating in a turbulent atmosphere. Then the influence of turbulence and source beam parameters on the beam propagation is studied in great detail. It finds that the intensity distribution of Gauss–Bessel beams will change into Gaussian profile in a turbulent atmosphere, and that stronger turbulence and smaller topological charges will lead to a faster changing.
