Maritime turbulence effect on the axial propagation properties of a Bessel higher-order cosh-Gaussian laser beam

Abstract

In this study, the axial propagation properties of the Bessel higher-cosh-Gaussian (BHChG) beam in maritime atmospheric turbulence are reported. Based on the extended Huygens-Fresnel principal, we extracted the analytical expression of the BHChG beam spreading in the considered medium. From our derived formula, we investigated numerical simulations to determine the maritime turbulence effect on the characteristics of the BHChG beam under various parameters of the maritime turbulence and the source beam. The obtained results show that the Gaussian waist, cosh parameter, wavelength, beam waist, inner scale and the refractive-index structure parameter, have an interesting effect on the propagation properties of this beam. Additionally, under suitable conditions various particular cases of the axial intensity of the BHChG beam have been derived from the derived result. The outputs of this study have potential applications in laser designators, optical communication systems and remote sensing.

Design and implementation of laser atmospheric transmission digital twin software system

“…The power density of the laser transmitted to the target decreases, which seriously restricts the application performance of advanced laser systems. The atmospheric state varies significantly with different geographical and climatic conditions and in different seasons [9,10] . In addition, advanced laser systems are very sophisticated and expensive, and some optoelectronic devices are fragile and environmentally sensitive.…”
