Effects of Hollow–Gaussian beams on Fresnel diffraction by an opaque disk

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

“…Overall, several theoretical and practical investigations have attracted the great attention of many optical researchers to different laser beams passing through oceanic turbulence for a long time, as evidenced by numerous studies (Chen et al 2013;Fu and Zhang 2013;Huang et al 2014;Ding et al 2015;Li et al 2019;Liu et al 2019;Liu et al 2017;Lu et al 2015;Ye et al 2018;Bayraktar 2020;Ata and Baykal 2018). Our research group has conducted a comprehensive study in this domain and has also contributed to examining this medium Saad et al 2023;Benzehoua and Belafhal 2023a;Lazrak et al 2022;Benzehoua et al 2023).…”

“…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).…”

Periodic properties of partially coherent generalized Hermite cosh-Gaussian beams through a gradient-index medium

“…However, through optical systems is crucial for enhancing imaging quality. Thus, propagation of light beam in various optical systems has sparked significant interest among numerous researchers (Benzehoua and Belafhal, 2022, Benzehoua and Belafhal, 2023, Saad et al 2024a. Specifically, researchers have delved into the propagation characteristics within a gradient index medium for different kinds of beams, including Ince-Gaussian beams (Gutierrez-Vega and Bandres 2005), Laguerre-Gaussian beams (Newstein and Rudman 1987), Airy-Gaussian beams (Deng 2011), hypergeometric laser beams (Kotlyar et al 2013), Elegant Ince-Gaussian beams (Bai et al 2011), Airy-Gaussian vortex beams (Zhao et al, 2016) Chirped Airy beams (Feng et al 2017), hollow sinh-Gaussian beams (Zou et al 2017), Bessel beams (Cao et al 2018), Bessel-Gaussian beam (Pei et al 2019), Gaussian vortex beams (Yang et al 2020), non-diffracting Lommel beams (Hui et al 2021), Generalized Humbert-Gaussian beam (Nossir et al 2023, Hollow higher-order cosh-Gaussian beam (Saad and Belafhal 2021), Whittaker-Gaussian laser beam (Nossir et al, 2023), lorentz-gauss vortex beam (Qusailah et al, 2023), Tricomi beams (Qiu et al, 2023) and more.…”

“…Encouraged by these characteristics, we recently developed the Generalized Hermitecosh-Gaussian beam (Saad and Belafhal, 2023 ;Saad et al, 2023a;Saad et al, 2023b;Saad et al, 2023c;Benzehoua et al, 2023a ;Benzehoua et al, 2023b) as a new class of partially coherent beams. By carefully selecting its parameters, this source has been shown to be versatile and capable of generating a wide range of random light sources.…”

Impact of Human upper Dermis tissue on the spectral intensity of a pulsed chirped General Model vortex higher-order cosh-Gaussian beam

“…Extensive studies in the literature have explored the propagation and evolution of laser beams and pulsed beams in various random media and optical systems, displaying their advantages (Hricha et al, 2021;Nossir et al, 2021;, 2023cBayraktar, 2022). Higher-order cosh-Gaussian beams evolve into Gaussian beams during atmospheric propagation and spread (Benzehoua & Belafhal, 2023d) and show focusing behavior in oceanic turbulence .…”
