在大气湍流斜程传输中拉盖高斯光束的轨道角动量的研究*
Study on orbital angular momentum of Laguerre-Gaussian b eam in a slant-path atmospheric turbulence
摘要
Abstract
Atmospheric turbulence can cause random variations of the refractive index, resulting in a spatial inhomogeneity. When a Laguerre-Gaussian beam is propagating through the atmospheric turbulence, spatial inhomogeneity can bring about the change of photon wave function that causes variations in the orbital angular momentum. This article discusses how turbulence media change the orbital angular momentum of photons as to form different photon states, when the Laguerre-Gaussian beam is propagating in a slant-path atmospheric turbulence, by calculating the weight of the spiral harmonic component of the beam energy. Analysis of the variations of orbital angular momentum of Laguerre-Gaussian beam in the turbulent medium has been carried out.关键词
