Abstract

Abstract: Focusing on numerical simulations of laser propagation in atmospheric turbulence, a method for determining the grid size of optical-field samples that need to be stored in a data file was first suggested, and a simulation scheme based on a parallel computer cluster was proposed. By performing simulation examples, both the average intensity of collimated fundamental Gaussian beams propagating through atmospheric turbulence and the change in spatial-mode composition of Laguerre-Gaussian (LG) beams travelling in atmospheric turbulence were studied. Analyses show that for the case of horizontal propagation, the use of a matching approach based on zero-order moment to determine the atmospheric coherence parameter associated with each random phase screen leads to greater simulation accuracy than the use of that based on higher-order moment; atmospheric turbulence results in inter-mode scattering of a propagated LG beam with its strength depending on the absolute turbulence level, transmitting-plane beam parameter, radial index and azimuthal index.
