径向偏振高阶贝塞尔-高斯涡旋光束在海洋湍流中的传输特性
Propagation Characteristics of Radially Polarized High-order Bessel-Gaussian Vortex Beams in Ocean Turbulence
摘要
Abstract
The intensity and scintillation characteristics of radially polarized high-order Bessel-Gaussian vortex beams in ocean turbulence were studied using the stepwise phase screen method.It was found that the intensity in the central region of a radially polarized high-order Bessel-Gaussian vortex beam is influenced by its intrinsic properties after travelling a certain distance.For ocean turbulence with varying intensities,the scintillation fac-tor in the axial region corresponding to the beam increases as the mean square temperature dissipation rate rises.Compared with linearly polarized beams and radially polarized beams,radially polarized high-order Bessel-Gaussian vortex beams are less affected by ocean turbulence.It was also found that,after propagating a certain beams,the higher the topological charge number(n≥1)of a radially polarized high-order Bessel-Gaussian vor-tex beam,the smaller the scintillation factor.Additionally,the radially polarized zero-order Bessel-Gaussian vortex beam(n=0)exhibits a lower scintillation factor compared to the radially polarized high-order Bessel-Gaussian vortex beam(n≥1).关键词
