“…In [8,9], the application of partially coherent beam in laser communication has been analysed, revealing that prior to the coherent models, the partially coherent beams can effectively control the bit error rate of the optical communication links. Therefore, there have been considerable research activities focusing on the partially coherent beams travelling through oceanic turbulence [10][11][12][13][14][15][16][17][18]. For instance, Hermite-sinusoidal-Gaussian beams are known to be derived from the paraxial wave equation, containing massive classes of beams like sinh-(or cosh-) Gaussian and sin-(or cos-) Gaussian types [19,20] and such beams propagating through oceanic water or optical system have been extensively studied [10][11][12][13][14][15][16][17][18].…”

The propagation behaviours of a sin-Gaussian beam (SiGB) with astigmatism in oceanic water is analysed. The analytical expressions for the average intensity of such a beam are derived by using the extended Huygens-Fresnel integral. Its average intensity and on-axial intensity distributions in oceanic water are numerically examined. Then, we mainly focus on the effect of the beam parameters and the medium structure constant on the propagation behaviours for the astigmatic SiGBs in oceanic water, revealing that the evolutions of the intensity distributions can be effectively modulated by adjusting the astigmatic parameter, coherence length and the atmosphere turbulence strength.

Abstract. Based on the extended Huygens-Fresnel principle, the analytical expressions for the Strehl ratio(S R ) of Gaussian Schell-model(GSM) vortex beams and Gaussian Schell-model non-vortex beams propagating through atmospheric turbulence and free space are derived. The corresponding results are also calculated. It is shown that the smaller the structure constant C 2 n , the inner scale l 0 and the wave length λ, as well as the larger the outer scale turbulence L 0 , the lager the S R for the GSM vortex beams, and as the spatial correlation length σ 0 increases, the S R for the GSM vortex beams first increases then decreases. The work will provide theoretical foundation for the practical application of GSM vortex beams.

“…In some applications such as free-space optics, the atmospheric turbulence severely influences the beam quality and therefore the efficiency of the technology. Historically, there has been great interest in studying the properties of laser beams propagating through turbulent atmosphere [1][2][3][4][5], and various types of laser beams, such as spatially fully coherent beams [6][7][8][9][10][11][12], spatially partially coherent beams [13][14][15][16][17][18], and laser array beams [19,20] have been considered. In addition, many investigations into the properties of laser beams in non-Kolmogorov turbulence have been reported [21,22].…”

The characteristic size of a collimated Gaussian beam propagating through 1-13 km atmospheric paths is investigated by simulating phase screens using the fast Fourier transform method. Taking a threshold into account, a method to derive a modified centroid and corresponding characteristic radii of the short-term spots is proposed. Effective radius, robust radius, sharpness radius, and maximum radius are analyzed by probability statistics. Furthermore, several parameters representing the energy content of the spots within each radius and the energy duty cycle of the maximum radius are studied. The study shows that, when the modified centroid is taken as a center, the effective radius is more suitable for application after a long propagation path, while the maximum radius is more effective for a short distance. However, when all effective subspots of a short-term image are investigated, the maximum radius is usually utilized, and the energy duty cycle represents the effect probability.
