Average power of Laguerre-Gaussian laser beams along the atmospheric path

Abstract

Numerical simulation of various mode propagation of a Laguerre-Gaussian laser beam reflected by a flat mirror at different intensities of optical turbulence along the atmospheric path are carried out. It is found that the strength of optical turbulence increases, the average power of the received signal at the end of a location path exceeds ones at the end of a propagation path double distance in the forward direction. The greater the mode order of the Laguerre-Gaussian beam, the stronger the effect.
