Spatial-Temporal Self-Focusing of Partially Coherent Pulsed Beams in Dispersive Medium
Applied Sciences, 2019 Partially coherent pulsed beams have many applications in pulse shaping, fiber optics, ghost imaging, etc. In this paper, a novel class of partially coherent pulsed (PCP) sources with circular spatial coherence distribution and sinc temporal coherence ...

Partially Coherent Flat-Topped Beam Generated by an Axicon
Applied Sciences, 2019 The intensity distribution of a partially coherent beam with a nonconventional correlation function, named the multi-Gaussian Schell-model (MGSM) beam, focused by an axicon was investigated in detail.
