Propagation of Gaussian Schell-model Array beams in free space and atmospheric turbulence

Intensity and Coherence Characteristics of a Radial Phase-Locked Multi-Gaussian Schell-Model Vortex Beam Array in Atmospheric Turbulence

“…Introducing a MGSM correlation [22], the CSD of a RPLMGSMV beam array with Q beamlets can be written as…”

“…From previous studies [1], one can see that partially coherent beams are resistance to the deleterious effects of turbulence. In past years, the properties, including intensity, polarization, and coherence, of Gaussian Schell-model (GSM) beams [15][16][17][18][19] and GSM beam array [20][21][22][23] propagating in turbulence were widely studied. On the other hand, the special correlated beams are also be introduced and analyzed, such as non-uniformly correlated beams [24], multi-Gaussian Schell-model (MGSM) beams [25][26][27][28], cosine-GSM beams [29], multi-cosine-Laguerre-Gaussian correlated Schellmodel beams [30].…”

Lissajous-like patterns generated by multi-cosine Gaussian-correlated Schell-model beams

“…As mentioned above, there have been two types of McGCSM beams introduced in previous studies. It has been proved that in the far field one exhibits square optical lattice [17,[24][25][26] and the other arrives the ring-shaped Gaussian array distribution or concentric closed ring-shaped pattern [22,23]. In this paper, we propose the third one which can generate a Lissajous-like transverse configuration during propagation.…”

“…Recently, several models of multi-cosine Gaussian-correlated Schell-model (McGCSM) beams whose source SDOCs are syntheses of many cosine functions have been introduced. It was found in [17,[24][25][26] that one model Abstract A class of random stationary, scalar sources producing far fields with Lissajous-like intensity profiles is introduced by modeling the source spectral degree of coherence (SDOC) as a multi-cosine Gaussian-correlated Schellmodel (McGCSM) function. Analytical expressions for the cross-spectral density generated by such sources on propagation through a stigmatic ABCD optical system are derived.…”

Propagation of Rectangular Multi-Gaussian Schell-Model Array Beams through Free Space and Non-Kolmogorov Turbulence

“…In free space communication, the properties of coherent array beams propagating in free space and turbulent atmosphere have been widely investigated [27][28][29][30]. According to previous work, the partially coherent beams can reduce the effects of turbulent atmosphere [31], thus the evolutions of partially coherent array beams in turbulence, such as Gaussian Schell-model array beams [3,[32][33][34], radial phase-locked array beams [35][36][37][38][39][40], and optical coherence vortex lattices [41], were also investigated. The multi-Gaussian Schell-model (MGSM) beams will evolve into flat-topped beams, thus the beams generated by a MGSM source have attracted much attention [42][43][44][45][46][47][48].…”
