Partially coherent sources with the combined quadratic phase

Propagation Properties and Application of Radially Polarized Partially Coherent Twisted Vortex Hermite‐Gaussian Schell‐Model Beams

“…From Figure 1a1-a4, we can intuitively find that the normalized intensity curve transitions from the initial double peak to the flat-top Gaussian profile as propagation distance increases, and finally appears as a Gaussian envelope in the far field. It is also noteworthy that the propagation images of S xx is similar to the previous work, [26] which is a good confirmation of our previous analysis that the RP-PCTVHGSM beam will degenerate into the RPPCTGSM beam with m = 0. When m is greater than 0, a vortex appears in the center of the beam, which can be explained through the mutual transformation between the Hermite function and the Laguerre function.…”

Asymmetric rotating array beams with free movement and revolution

“…Distorted partially coherent beams have also made some important conceptual developments in recent years [14][15][16][17] . In order to achieve larger degrees of freedom and flexibility in the beam twist, several types of typical partially coherent beams have been introduced recently [18,19] . The sign of the propagation process is that the spectral density and coherence tend to rotate.…”
