Abstract
The effects of asymmetry atmospheric eddies on the beam spreading and wander of Bessel–Gaussian (BG) beams in anisotropic turbulence are studied. Results show that turbulence anisotropy leads to the declines in both beam spreading and wander of BG beams in the atmosphere. A BG beam with larger beam shape parameter η has a narrower spot size in a short-distance range and a wider spot size in a long-distance range. The effective Rayleigh ranges of BG beams for every turbulent situation decrease with the beam shape parameter η . When η is larger than 10, atmospheric turbulence has a negligible effect on effective Rayleigh range. The effective Rayleigh range and beam spreading increase and beam wander decreases as topological charge increase. Beam spreading is mainly affected by turbulence inner-scale, and outer-scale evidently affects beam wander in the atmosphere.
