“…In recent years, major research efforts have been devoted to the theoretical study of propagation of special beams in atmospheric turbulence, including vortex laser beam, vortex cosine hyperbolic Gaussian beam, airy prime beam, lowest order Bessel Gaussian beams, high power partially coherent laser beams, low order Laguerre-Gaussian beams, Bessel-Gaussian-Schell model beam, vortex Bessel-like beams, optical bottle beam, radial phased-locked rotating elliptical Gaussian beam array, airy Gaussian vortex beam array, flat-topped Gaussian vortex beam, generalized Bessel-Laguerre-Gaussian beams, and so on. Furthermore, the atmospheric turbulent effects involve mean intensity, scintillation, coherence, beam spreading, wander, and other propagation properties [31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46][47].…”

The Earth’s atmosphere is the living environment in which we live and cannot escape. Atmospheric turbulence is a typical random inhomogeneous medium, which causes random fluctuations of both the amplitude and phase of optical wave propagating through it. Currently, it is widely accepted that there exists two kinds of turbulence in the aerosphere: one is Kolmogorov turbulence, and the other is non-Kolmogorov turbulence, which have been confirmed by both increasing experimental evidence and theoretical investigations. The results of atmospheric measurements have shown that the structure of atmospheric turbulence in the Earth’s atmosphere is composed of Kolmogorov turbulence at lower levels and non-Kolmogorov turbulence at higher levels. Since the time of Newton, people began to study optical wave propagation in atmospheric turbulence. In the early stage, optical wave propagation in Kolmogorov atmospheric turbulence was mainly studied and then optical wave propagation in non-Kolmogorov atmospheric turbulence was also studied. After more than half a century of efforts, the study of optical wave propagation in atmospheric turbulence has made great progress, and the theoretical results are also used to guide practical applications. On this basis, we summarize the development status and latest progress of propagation theory in atmospheric turbulence, mainly including propagation theory in conventional Kolmogorov turbulence and one in non-Kolmogorov atmospheric turbulence. In addition, the combined influence of Kolmogorov and non-Kolmogorov turbulence in Earth’s atmosphere on optical wave propagation is also summarized. This timely summary is very necessary and is of great significance for various applications and development in the aerospace field, where the Earth’s atmosphere is one part of many links.

“…This attraction is a result of its wide applications in different fields, such as optical communication, information encoding, transmission, and lattice spectroscopy (Yadav et al 2007a(Yadav et al , 2007b(Yadav et al , 2008Han 2009). Several scientists, including our research group, have developed large-scale studies in this area (Cai 2006;Zhou and Chu 2009;Yang et al 2009;Wang et al 2010;Zhao and Cai 2011;Zhong et al 2011;Khannous et al 2015;Ez-Zariy et al 2016;Boufalah et al 2018;Ye et al 2019;Chib et al 2020;Hricha et al 2021aHricha et al , 2021bLazrek et al 2021;Nossir et al 2021;Chib et al 2022;Nabil et al 2022aNabil et al , 2022bNabil et al , 2022c.

Presenting the intensity development of a circular Laguerre-cosh-Gaussian (CLChG) beam in turbulent mouse biological tissues is the major goal of the current work. Using the power spectrum refractive index from Schmitt's model and the extended Huygens-Fresnel integral, the propagation formula of the CLChG beam is produced. In order to determine the spreading properties of the studied beam, analytical expressions of the CLChG beam's effective beam size in turbulent mouse biological tissues are constructed. Some graphical representations have to be carried out in order to discover the impacts of beam and biological turbulence parameters on this sort of beam. The findings show that the transformation of the CLChG beam into a Gaussian-like beam in the far field occurs more quickly when the beam passes through the deep dermis of the mouse. The shape of the CLChG beam can also be changed by choosing a specific value for the parameter linked to the cosh-part. Because the effective beam spot radius along the x-and y-axis are equal, we also see that the beam spot in biological tissues takes on a circular shape.

“…Research on the propagation characteristics of optical beams through atmospheric turbulence has grown in interest because it has important applications, including free‐space optical communication, laser radar, remote sensing, laser range finder, laser designator, and imagery, for the sake of research, our group was interested in this field. [ 2–11 ] Moreover, in oceanic turbulence, the propagation properties of a controllable rotating elliptical Gaussian optical coherence lattice have been reported. [ 12 ] Additionally, it has been demonstrated that partially coherent beams help improve the resistance to turbulent media; thus, they have important applications in the systems listed above.…”

This work investigates the joint effects of jet engine exhaust‐induced turbulence and atmospheric turbulence on the propagation of a partially coherent Gaussian Schell‐model Array (GSMA) vortex beam. Using the two‐process propagation method, analytical formulae are derived for the cross‐spectral density, spectral density, degree of coherence, and beam width of the considered beam. The results show that the considered beam takes different shapes; when the spatial coherence is large, the spectral density of the GSMA vortex beam takes an elliptical shape, whereas when the spatial coherence is smaller, the spectral density remains a Gaussian shape. The evolution profile of the degree of coherence weakens gradually when the propagation distance, topological charge, and turbulence strength increase. Moreover, the profile of the degree of coherence takes the Gaussian profile when the propagation distance is longer or turbulence atmospheric is stronger. Furthermore, the results reveal that the corresponding beam spreads faster with a larger propagation distance, lower spatial coherence, and high‐strength turbulence. This study also concludes from the results that the beam is affected more when its propagation is near the jet engine exhaust, which means that this latter has a significant impact.
