Beam Quality Factor of Partially Coherent Airy Beam in Non-Kolmogorov Turbulence
Atmosphere, 2022 A universal formula of the beam quality factor for a partially coherent Airy (PCA) beam in non-Kolmogorov turbulence has been investigated. Results of numerical simulation display that expanding the internal scales of non-Kolmogorov turbulence is good ...

Partially coherent stable and spiral beams [PDF]
Journal of the Optical Society of America A, 2013 Stable and spiral coherent beams, which do not change the form of their intensity distribution apart from possible scaling and rotation during propagation and therefore possess self-healing properties, are widely applied in science and technology. On the other hand, it has been found that partially coherent light often provides better output than ...

Propagation of partially coherent radiation using Wigner functions
Physical Review Accelerators and Beams, 2021 Undulator radiation from synchrotron light sources must be transported down a beam line from the source to the sample. A partially coherent photon beam may be represented in phase space using a Wigner function, and its transport may use some similar ...

Propagation Properties of a Twisted Hermite-Gaussian Correlated Schell-Model Beam in Free Space
Frontiers in Physics, 2022 We introduce a novel type of twisted partially coherent beams with a nonconventional correlation function, named the twisted Hermite-Gaussian correlated Schell-model (THGCSM) beam.

Scattering of partially coherent vortex beam by rough surface in atmospheric turbulence.
Optics Express, 2022 A double-passage propagation model of partially coherent Laguerre-Gaussian (LG) vortex beams with orbital angular momentum (OAM) modes in turbulent atmosphere after scattering from Gaussian rough surfaces was formulated.

Beam focus modifications by cropping partially coherent X-ray beams
, 2022 We simulate the focusing of a partially coherent X-ray beam emitted by an undulator in a fourth-generation storage ring by performing a coherent mode decomposition and wave optics propagation.

Partially Coherent Off-Axis Double Vortex Beam and Its Properties in Oceanic Turbulence
Photonics, 2023 A partially coherent off-axis double vortex beam (PCOADVB) composed of two off-axis vortices is theoretically presented. The analytical equations of a PCOADVB in oceanic turbulence are presented, and the intensity profiles and the number of coherence ...
