摘要

We investigated the scintillation index of the Laguerre-Gaussian beam (LGB) propagating in a turbulent marine atmospheric medium using the Rytov theory. We derived the scintillation index’s analytical expression and plotted the results beam radius, inner scale, operating wavelength, turbulence strength, and radial mode number. We observed the rise in the scintillation index as the accumulated turbulence increased along the propagation path. The numerical results show that the scintillation index of the LGB depends on these factors. We anticipate that the scintillation index of the LGB in the Von Karman maritime power spectrum will be useful for the optical wireless communication system and laser radar developers.
