Theoretical investigation on the Hollow Gaussian beams propagating in atmospheric turbulent

Atmospheric turbulent effects on the propagation properties of a general model vortex higher-order Cosh-Gaussian beam

“…Also, the so-called dark hollow beams with zero central intensity have attracted great attention in the past years because of their wide applications in optical trapping particles (Kuga et al 1997;Paterson et al 2001). The research topics in this direction are many and varied, among them, the vortex of the flat-topped, Gaussian, Airy Gaussian, multi-hyperbolic Sine-correlated, and the Bessel-like beams (He & Lü 2011;Filimonov et al 2016;Ez-zariy et al 2016b, Khannous et al 2016Yue et al 2019;Elmabruk & Eyyubolu 2019;Song et al 2020;Lukin 2020). Furthermore, in two separate papers, Hricha and co-authors (2021a; have studied the effect of the turbulent atmosphere on the propagation properties of the vortex cosine hyperbolic Gaussian and Hermite-cosine-hyperbolic-Gaussian beams.…”

Propagation of vortex cosine-hyperbolic-Gaussian beams in atmospheric turbulence

“…In recent years, the propagation of laser beams in atmosphere have received a great attention from the laser researchers due to many applications such as the remote sensing, imaging, optics communications and so on [1][2]. The propagation characteristics of laser beams with various excitations in the atmospheric turbulence have been examined [3][4][5][6][7][8][9][10][11][12][13][14], and also new beam models have been discovered and studied for their applications in free space optical communication systems. Among them, one can cite the hollow vortex Gaussian beam which is a fundamental Gaussian beam including a topological vortex charge [15].…”

Behavior of the Central Intensity of Generalized Humbert-Gaussian Beams Against the Atmospheric Turbulence

“…The propagation properties of elegant Laguerre-Gaussian beams [4], Laguerre-Gaussian Beams [5], flat-topped vortex hollow beams [6], Laguerre-Gaussian Schell beams [7], truncated Bessel-Gauss beams [8], partially coherent Bessel-Gaussian beams [9] and Hypergeometric-Gaussian beams [10] and so on, have greatly developed by the considered authors. On the other hand, in our research group Khannous et al have interested to the propagation characteristics of some laser beams in turbulent atmosphere such as: Kummer beams [11], Hypergeometric-Gaussian beams Type II [12] and Hollow-Gaussian beams [13]. Hennani et al [14] have studied the axial intensity distribution of the modified quadratic Bessel-Gaussian beam in turbulent atmosphere.…”
