Laser Gaussian beam analysis of structure constant depends on Kolmogorov in turbulent atmosphere for a variable angle of wave propagation

Abstract

Laser Gaussian beam propagation is important in optical communications; the challenges of the measured constant parameters are varied angle wave propagation, the receiver plan in the slant path of laser Gaussian beam (G) in Kolmogorov gauges, and the effect of the laser in a random medium. At this point, atmospheric turbulence is reputable based on laser Gaussian beam propagation. Moreover, the space propagation of Gaussian beam waves of higher-order Gaussian beam modes has been expanded from the effects of the scintillation index and with different zenith angles between the laser propagator and the detector (receiver) in the ramp path. Furthermore, in the Cartesian coordinate system, the scintillation index in the Kolmogorov standard is evaluated, and it employs two methods; first, Huygens–Fresnel fundamental and, second, random phase screen for work synchronization. Additionally, to analyze the contour parameters of constant construction, the intensity and receiver field is found to compute the high turbulent modes in the atmospheric deposition, which depends on propagation distances. These result in significant reserves in the matlab computation period and serve the imitation for enhancement of the link transmission; therefore, the zenith angle and scintillation index are pretentious by slant beam, and they enhance the performance that makes the comparisons found with fixed structure constant parameters [Formula: see text] and the propagation distance against the scintillation index.

“…Finally, we were detected that the scintillation index is acted the best results in elevations between 0& 7.566km which is indicated in the point spot along the different altitudes, distances, source sizes, and BER, to sum up, the fallouts and figs which are evoked above is agreed with ref [3,8,27].

“…These studies of aperture laser beam [3] spreading via the perturbation media in space [4]. So as the Gaussian beam propagation with varied angles [5], and related to properties [6], which phase changing [7] besides, the reduction of the signal occurred in the atmosphere layer of the laser beam due to an absorption and scattering process [8]. Until now, the individual limited papers were dedicated to the vortex beams' excellence in the turbulent atmosphere [9], moreover, study the Bessel Gaussian parameters [10].…”
