Partially coherent Mathieu–Gauss beams [PDF]

open access: yesScientific Reports
We present a theoretical study and experimental generation of Mathieu–Gauss beams in the partially coherent regime. By means of a rotating ground glass diffuser and a spatial light modulator, we demonstrate independent control over both the spatial ...

Experimental synthesis of partially coherent beam with controllable twist phase and measuring its orbital angular momentum [PDF]

open access: yesNanophotonics, 2021
Twist phase is a nontrivial second-order phase that only exists in a partially coherent beam. Such twist phase endows the partially coherent beam with orbital angular momentum (OAM) and has unique applications such as in super-resolution imaging. However,

Assessing the impact of spatial coherence on the sinusoidal linear Fresnel zone plate’s depth of focus [PDF]

open access: yesScientific Reports
This research examines, using both theory and experimentation, how a light beam’s spatial coherence affects a sinusoidal linear Fresnel zone plate’s depth of focus.

Average Intensity of a Laguerre—Gaussian Vector Vortex Beam through Inhomogeneous Atmospheric Turbulence

open access: yesPhotonics, 2023
We investigate the evolution properties of a partially coherent Laguerre–Gaussian vector vortex (LGVV) beam through inhomogeneous atmospheric turbulence. Analytical formulae for the elements of a cross-spectral density matrix of a partially coherent LGVV

Abnormally autofocusing vortex Swallowtail Gaussian vector beam with low spatial coherence

open access: yesNew Journal of Physics, 2023
The precondition for the application of light beams is the ability to devise light distribution with high precision. Controlling more dimensions for structured light fields is an effective method to improve the ability to devise light distribution.

Beam Quality Factor of Partially Coherent Airy Beam in Non-Kolmogorov Turbulence

open access: yesAtmosphere, 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 ...

Propagation of partially coherent radiation using Wigner functions

open access: yesPhysical 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 ...
