Propagation of BesselGaussian Beam with Optical Vortices in Turbulent Atmosphere
Based on the extended HuygensFresnel integral, the analytic expressions for BesselGaussian beams (BGBs) with optical vortices propagating in turbulent atmosphere are derived. The average intensity properties and the beam quality (Power in bucket) in the far field of BesselGaussian beams with optical vortices propagating in turbulent atmosphere are investigated. It is found that intensity profiles of BesselGaussian beams experienced successive variations and the phase singularity rapidly fades away during propagating in turbulent atmosphere. The process is closely related with the number of topological charge, the beam′s waist width and the strength of atmospheric turbulence. The maintenance of singularity of vortex beams with larger topological charge in turbulent atmosphere is better than that for vortex beams with smaller topological charge. In addition, based on the theory of power in bucket, the influence of topological charge, the beam′s waist width and the strength of atmospheric turbulence on the beam quality of BesselGaussian beams is explored in detail.
