We theoretically investigate the propagation properties of a Laguerre higher order cosh Gaussian beam (LHOchGB) in a fractional Fourier transform (FRFT) optical system. Based on the Collins formula and the expansion of the hard aperture function into a finite sum of Gaussian functions, we derive analytical expressions for a LHOchGB propagating through apertured and unapertured FRFT systems. The analysis of the evolution of the intensity distribution at the output plane has shown from the obtained expressions, using illustrative numerical examples.The results show that the intensity distribution of the considered beam propagating in FRFT is significantly influenced by the source beam parameters and the parameters of the FRFT system.It is possible to demonstrate the potential benefits of the results obtained for applications in laser beam shaping, optical trapping, and micro-particle manipulation.

“…Received beam profiles can be adjusted by modifying its configuration, which makes it ideal for a wide range of applications (Benzehoua and Belafhal, 2023a;2023b;2023c;Benzehoua et al, 2023;Saad et al, 2024;Benzehoua et al, 2024). The interaction between the beam in question and a uniaxial crystal offers promising prospects for generating vortex beams, thus paving the way for potential applications in the field of optical communication.…”

In this study, we examine the propagation characteristics of Laguerre Higher Order Cosh-Gaussian beam (LHOchGB) in uniaxial crystals. Utilizing integral of Huygens-Fresnel, analytical expression of the LHOchGB in the considered crystal is derived. During beam propagation, our analyses are performed using numerical simulations under different parameters to investigate the impact of beam parameters and crystal refractive indices on the received beam. The obtained results demonstrate that the features of the incident beam and the crystal's refractive indices can be adjusted to control the intensity and phase distributions of the corresponding beam. We anticipate that the insights gleaned from our research will prove valuable for controlling optical particles.

“…There has long been a great deal of theoretical and practical interest in the propagation of laser beams over atmospheric turbulence (Hajjarian et al, 2010;Gbur et al, 2014;Benzehoua et al, 2023b;Chib et al, 2020;Nossir et al, 2021Nossir et al, , 2023a. Due to the intricacy of oceanic turbulence, laser beam propagation through it is comparatively less studied than that via atmospheric turbulence.…”

The purpose of this paper is to explore the evolution behavior of two important laser features: the Bessel higher-order cosh-Gaussian (BHoChG) beam and the Bessel higher-order sinh-Gaussian (BHoShG) beam propagating through turbulent oceanic environments.Benefiting from the extended Huygens-Fresnel principle, the analytical formulas for the average intensity of the beams passing through oceanic turbulence are derived. The propagation of some laser beams through oceanic turbulence is also deduced as particular cases from the present study. The effects of oceanic turbulence parameters and the source beam parameters are examined to understand their influence on the intensity distribution of the considered beams by using numerical simulations. Our results show that the spreading of these beams depends on their initial parameters and oceanic parameters. Hence, the propagation of the studied beams through oceanic turbulent will be faster with the smaller dissipation rate of the mean square temperature, larger salinity fluctuations, higher rate of dissipation of turbulent kinetic energy per unit mass of fluid and with decreasing the beam width and the parameter  . The outputs of this study have useful applications in optical underwater communication, remote sensing, imaging and others.
