“…Recently, several campaigns have experimentally measured the presence of anisotropy turbulence near the ground [19,20]. Many works on the propagation properties of partially coherent beams in anisotropic non-Kolmogorov turbulent atmospheric have been extensively investigated [21][22][23][24].…”

In this paper, we investigated the influence of a turbulence jet engine exhaust on Laguerre-Gaussian correlated shell-model beams (LGSMBs). The analytical formulae of the cross-spectral density function as well as the beam width are derived based on the Huygens-Fresnel diffraction principle and the second-order moments of the Wigner distribution function, respectively. From our main results, the spectral density, the degree of coherence and beam width of a LGSMB are analyzed numerically. It is found that for high source coherence width, the spectral density changes gradually its profiles from circular to elliptical shape at short propagation distance, then the beam transforms into a well like Gaussian at long propagation distance. Although, at very short propagation distance, the beam becomes an elliptical dark hollow if the source coherence is very lower. Also, the numerical results show that the LGSMB spreads more rapidly than the GSMB in the same conditions.

“…In past years, the topic of beams propagating in atmospheric turbulence has been explored, and different models, such as Kolmogorov and non-Kolmogorov turbulences, were given to describe the atmosphere. The propagation properties of beams, such as average intensity, polarization, scintillation index, and degree of coherence, were widely investigated in Kolmogorov turbulent atmosphere [1][2][3][4][5][6][7][8][9][10][11] and non-Kolmogorov turbulence [12][13][14][15][16][17][18][19][20][21][22].…”

In this paper, rectangular multi-Gaussian Schell-model (MGSM) array beams, which consists N×D beams in rectangular symmetry, are first introduced. The analytical expressions of MGSM array beams propagating through free space and non-Kolmogorov turbulence are derived. The propagation properties, such as normalized average intensity and effective beam sizes of MGSM array beams are investigated and analyzed. It is found that the propagation properties of MGSM array beams depend on the parameters of the MGSM source and turbulence. It can also be seen that the beam size of Gaussian beams translated by MGSM array beams will become larger as the total number of terms, M, increases or coherence length, σ , decreases, and the beam in stronger non-Kolmogorov turbulence (larger α and l 0 , or smaller L 0 ) will also have a larger beam size.
