“…The Schell model type is currently the foundation for the majority of investigations on the structure of the partially coherent light source. Since Gori et al established the necessary requirements for a valid CSD function [3,4], much consideration and discussion have been given to the studies of the spatial correlation structure of partially coherent sources, and a number of partially coherent beam models with extraordinary correlation structures have been put forth by later researchers [5,6]. Furthermore, it was discovered that special correlated structured beams are superior to conventional correlated structured beams in terms of their many distinctive transmission qualities, such as nonuniform correlated Schell model (NUCSM) beams with a self-focused, self-shifted effect in transmission [7,8]; multi-Gaussian Schell model (MGCSM) beams with circularly symmetric flat-topped intensity distribution in the far field [9][10][11]; and cosine Gaussian Schell model (CGSM) sources form a dark hollow light intensity distribution after transmission over a distance [12].…”

We propose a new partially coherent vortex source model in which the spatial correlation function is a sinc function on the difference from the q-th power of the coordinates of two points of the source field. The beam radiated by such source is termed the high-order sinc-correlated model vortex (SCMV) beam. We derived the propagating formula of the cross-spectral density (CSD) function for SCMV beams in atmospheric disturbances. On the basis of the derived analytical expression, the behavior of the spectral density of the SCMV beams propagating in free space and atmosphere turbulence was investigated under comparative analysis. The results show that the spectral densities of such beams exhibited interesting novel features, which were significantly different from those of the trivial vortex beams.

“…In [7], the possibility of substituting a coherence state with a nonlinear phase by a linear combination of those with linear phases is suggested, a method that could be used for theoretical work and the design of elementary (linear) phase devices of correlation optics. Due to the recent wide-spread use of manipulation of optical fields with the high spatio-temporal resolution devices (e.g., spatial light modulators), it became possible not only to computer-simulate light fields with arbitrary statistics but also to implement them in real-light systems.…”
