Characteristics of Gaussian vortex beam in atmospheric turbulence transmission
摘要
Abstract
In order to research the influence of Gaussian vortex beam transmission on atmospheric turbulence , the radial average power and normalized average power distribution of the Gaussian vortex orbital angular mo -mentum(OAM) states after atmospheric turbulence as well as the intrinsic mode index , initial beam radius and turbulence intensity were theoretically analyzed .The validity of pure phase perturbation approximation was used to numerically simulate the variation of radial average power distribution of OAM mode during the trans-mission of Gaussian vortex beam .The transmission model was established and the atmospheric laser field transmission experiments were conducted .The simulated and measured OAM normalized average power distri-butions were compared .The results show that under the condition of weak turbulence , the radial average pow-er of OAM mode changes with the increase of receiver aperture size , and tends to be stable .For the common receiver aperture , the interference with OAM mode is very serious under strong turbulence or small initial beam radius .The reliability of numerical simulation of the mode change of OAM in turbulent media is veri-fied.The paper also verifies the reliability of numerical simulation of the mode change of OAM in turbulent media.关键词
