Holographic beam shaping of partially coherent light. [PDF]
Optics Letters, 2021 We present an algorithmic approach for holographic shaping of partially coherent light, which is described by a mode expansion containing thousands of individual modes. Using gradient descent and algorithmic differentiation, our algorithm is able to find

Partially coherent fractional vortex beam.
Optics Express, 2018 We introduce a new kind of partially coherent vortex (PCV) beam with fractional topological charge named partially coherent fractional vortex (PCFV) beam and derive the propagation formula for such beam passing through a stigmatic ABCD optical system ...

Partially coherent radially polarized fractional vortex beam.
Optics Express, 2020 A new kind of partially coherent vector beam, named a partially coherent radially polarized fractional vortex (PCRPFV) beam, is introduced as a natural extension of the recently introduced scalar partially coherent fractional vortex beams [Zeng et al ...

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 ...

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 ...

Digital in-line holography with a spatially partially coherent beam [PDF]
Journal of the European Optical Society-Rapid Publications, 2011 We propose in this paper an analytical solution to the problem of scalar diffraction of a partially coherent beam by an opaque disk. This analytical solution is applied in digital in-line holography of particles. We demonstrate that the reconstruction by

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.
