“…Henceforth, the Bessel higher-order cosh-Gaussian (BHoChG) beam has been successively introduced and examined by our research group (Nossir et al 2023b, Dalil-Essakali et al 2023. The specificity of this field is that the BHoChG beam is known to be a generalized form and the BHoShG beam can be a limiting case of this field.…”

Aiming at the Bessel higher-order cosh-Gaussian (BHoChG) beam and the Bessel higher-order sinh-Gaussian (BHoShG) beam, we investigate their propagation properties through turbulent biological tissues. In this respect, the analytical expression of the considered beams is obtained and developed, based on the extended Huygens-Fresnel integral. By numerical simulation, the intensity distributions of these beams for biological tissue types including intestinal epithelium and deep dermis of mouse in addition the human upper dermis versus the propagation distance as a function of the variations of the laser beam parameters. The obtained results indicate that the resistance of our beams against turbulent biological tissues increases as the source parameter increases counting the decentered parameter, the beam-order of the considered beams and the beam waist width. The findings show that the intensity distribution of the propagation of these beams occurs more quickly when they pass through the deep dermis of the mouse. The results presented in this paper are significant due to their potential application in determining the deterioration or disruption of biological tissue, medical imaging and medical diagnosis.

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.

“…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.…”

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.
