Axial intensity of Bessel higher-order cosh-Gaussian beam propagating in a turbulent atmosphere

Abstract

In the present paper, the effects of the turbulent atmosphere on the propagation properties of Bessel higher-order cosh-Gaussian (BHChG) beam are investigated. Based on the Rytov approximation and the extended Huygens-Fresnel integral diffraction, analytical expression of the axial intensity for BHChG beam is evaluated and the results of some laser beams are deduced as particular cases from our research. Some graphical representations have been carried out to study the influence of the incident beam parameters and the atmospheric turbulence on the considered beam. The obtained results can be useful for atmospheric optics applications in free-space optical communications.

Analyzing the effect of oceanic turbulence on spreading properties of the Whittaker-Gaussian laser beam

“…Thus, research on random fluctuations such as biological tissues and atmospheric conditions is required. Therefore, the impact of laser beams traveling around various turbulence mediums have been extensively examined in various studies (Nossir et al 2021;Dalil-Essakali et al 2023;Chib et al 2022;Benzehoua and Belafhal 2023b;Ebrahim et al 2023;Augustine and Chetty 2014).…”

Evolution behavior of pulsed chirped Laguerre higher-order cosh-Gaussian beam propagating through liver tissue

“…In recent decades, the study of laser beam propagation through turbulent environments has gained significant traction due to its diverse applications in laser communications, remote sensing, laser radar, and optical weaponry, among other fields. A multitude of research endeavors have delved into various characteristics of laser beams in turbulent media, encompassing phenomena such as beam wander, beam spreading, scintillation index, intensity distribution, and field correlations (Wu et al 2016;Korotkova et al 2012;Hricha et al 2021;Baykal 2021;Nossir et al 2023;Saad et al 2023a;Schmidt, 2010;Andrews et al, 2001, Bayraktar, 2021aVoelz, 2011).…”

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

“…More recently, a new family of laser beams called the Bessel higher-cosh-Gaussian (BHChG) beam (Nossir et al 2023b;Dalil-Essakali et al 2023) which is derived from the Laguerre higher-order cosh-Gaussian (LHChG) beam (Benzehoua and Belafhal 2023aand 2023c. The BHChG beam is a light beam model developed to describe a laser beam including Bessel cosh-Gaussian, Bessel-Gaussian and Gaussian beams.…”

“…On the other hand, the spreading of laser beams in a turbulent atmosphere attracted much attention from researchers thanks to its significance applications in laser defense and communication (Nossir et al 2021;Nossir et al 2023a;Dalil-Essakali et al 2023;Belafhal et al 2011;Boufalah et al 2018 andElmabruk et al 2019). Therfore, it initially motivated the development of physics (Eckart and Ferris 1956;Peixoto and Oort 1984) since the first working laser beam was introduced in 1960 (Maiman 1960).…”
