Theoretical analysis of Laguerre-Whittaker-Gaussian beams propagation in a turbulent atmosphere
摘要
This research examines the spread of Laguerre-Whittaker-Gaussian beams (LWGBs) in a turbulent atmosphere. Using the extended Huygens-Fresnel integral formula and Rytov theory, we derive a theoretical expression for the axial average intensity of LWGBs propagating in atmospheric turbulence. The profile of this axial intensity is analyzed numerically as a function of several parameters, including beam order, width of the beam size, turbulence strength, topological charge, and wavelength. The results demonstrate that the beam’s evolution is significantly influenced by the turbulence force
