Beam wander of array beams propagating through anisotropic turbulent atmosphere

Abstract

Abstract: Based on the extended Huygens-Fresnel principle, the analytical expressions of the beam width and beam wander for radial array beams in anisotropic turbulent atmosphere are derived. The numerical analysis results show that the beam wander of radial array beams is influenced by the number of Gaussian beam small, but the radius of the ring is large. There is small beam wander for radial array beams with the large radius of the ring. Beam wander is also mainly affected by the power law and anisotropic factor in anisotropic turbulence. At the same conditions, laser array beams in anisotropic turbulent atmosphere are less disturbed than Gaussian beam.

Key words: atmospheric optics, beam wander, extended Huygens- Fresnel principle, radial array beams
