Scintillation index analysis of generalized Bessel-Laguerre-Gaussian beam

In this paper, we present a detailed investigation of the Generalized Bessel-Laguerre-Gaussian (GBLG) beam propagating in a maritime turbulent atmosphere. Based on the born approximation and the Rytov theory with the use of the Von Karman spectrum, the scintillation index of the GBLG beam is evaluated and examined numerically. The obtained results indicate that the comportment of the GBLG beam is influenced by the turbulent strength, the inner scale of the maritime turbulent atmosphere, and the input beam parameters. The scintillation indexes of Laguerre-Bessel-Gaussian, Laguerre-Gaussian, Bessel-Gaussian and Gaussian beams through the considered medium are deduced as particular cases from our study.
