| Abstract: | 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. |
