Propagation properties of partially coherent Hermite–cosh-Gaussian beams through atmospheric turbulence

Effective radius of curvature of partially coherent Hermite–Gaussian beams propagating through non-Kolmogorov turbulence

“…The effective radius of curvature of PCHG beams with longer wavelength , larger beam order m, smaller beam waist width w 0 , or worse spatial coherence (smaller coherent parameter ) is less affected by the non-Kolmogorov turbulence. As compared with the results reported in [9,25,26], it can be readily seen that the effective radius of curvature of PCHG beams exhibits a similar variation behavior with , z, , m and in non-Kolmogorov turbulence as the beam width does, whereas it is not the case for the variation with w 0 , and the beam spreading always spreads in turbulence, so that the relative beam spreading is larger than 1, while R xr ðz, Þ 5 1 in turbulence. The results obtained in this paper would be useful for a further study and comparison of the variation behavior of beam characteristic parameters of different types of beams in nonKolmogrov turbulence.…”

“…Laser beam propagation through atmospheric turbulence has found wide applications in remote sensing, tracking, long-distance optical communications, etc., and has been studied extensively [1][2][3][4][5][6][7][8][9][10]. It is known that partially coherent beams are less sensitive to the effect of turbulence than fully coherent ones [1][2][3].…”

Comparative analysis of some Schell-model beams propagating through turbulent atmosphere

“…In recent years, the propagation of laser beams in a turbulent atmosphere has attracted much attention from researchers [1][2][3][4][5][6][7] due to their large applications such as in free space communications [8], active optical imaging [9], and remote sensing [10]. Furthermore, the specific nature of partially coherent laser beams has led to their extensive study in turbulent atmosphere by many authors [11][12][13][14][15][16][17][18][19][20][21]. Lu et al [17] have interested to the change of degree of coherence of partially coherent Gaussian Schell-model beam during its propagation in a turbulent atmosphere.…”

Changes of propagation characteristic parameters for partially coherent Hermite–Gaussian beams in a turbulent atmosphere

“…partially coherent Hermite-Gaussian (PCHG) beams, have been paid considerable attention [7][8][9][10][11][12][13][14]. For example, based on the quadratic approximation of the phase structure function, Yang et al [9,10], Ji et al [11] and Chen et al [12] investigated the beam spreading (or the spatial correlation property) for PCHCG and PCHG beams propagating through atmospheric turbulence. Using the Wigner distribution function (WDF), Ji et al obtained also the closed-form expression for the effective radius of curvature of PCHG beams in turbulence [13].…”
