Coherent-mode decomposition of partially polarized, partially coherent sources [PDF]
Journal of the Optical Society of America A, 2003 It is shown that any partially polarized, partially coherent source can be expressed in terms of a suitable superposition of transverse coherent modes with orthogonal polarization states.

Partially coherent ultrafast spectrography. [PDF]
Nat Commun, 2015 International audienceModern ultrafast metrology relies on the postulate that the pulse to be measured is fully coherent, that is, that it can be completely described by its spectrum and spectral phase.

Coherent and partially coherent twisting beams
Optical Review, 1994 We present coherent and partially coherent beams that exhibit transverse pattern expansion and rotation upon free propagation. Coherent twisting beams may be generated by a suitable superposition of Laguerre-Gauss modes, while a model for partially ...

Twisting partially coherent light
Optics Letters, 2018 Twisted Gaussian Schell-model beams were introduced 25 years ago as a celebrated example of a “genuinely two-dimensional” partially coherent wavefield.

Coherence vortices in partially coherent beams
Optics Communications, 2003 It is demonstrated that the spectral degree of coherence of a partially coherent beam may possess isolated pairs of points at which its phase is singular, and that in the neighborhood of these points the phase may possess a vortex structure.

Partially coherent sources with circular coherence [PDF]
Optics Letters, 2017 A new class of partially coherent light sources is introduced. At the source plane, they exhibit perfect coherence along any annulus that is concentric to the source center. Between two points at different distances from the center, coherence can be partial or even vanishing.

Photonics, 2021 A new family of partially coherent pulsed beams with spatial cosine-Gaussian and temporal Laguerre–Gaussian correlations, named spatial cosine-Gaussian and temporal Laguerre–Gaussian correlated Schell-model (SCTLGSM) pulsed beams, is introduced.

Beam Properties of a Partially Coherent Beam Propagating Horizontally in Atmospheric Turbulence
Photonics, 2023 This study explored the impact of atmospheric turbulence on partially coherent light propagation. Atmospheric turbulence causes random modulation of the intensity and phase of light, resulting in a speckle pattern in the far field.

Abnormally autofocusing vortex Swallowtail Gaussian vector beam with low spatial coherence
New 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.

Enhancement of Partially Coherent Diffractive Images Using Generative Adversarial Network
AI, 2022 We present a deep learning-based generative model for the enhancement of partially coherent diffractive images. In lensless coherent diffractive imaging, a highly coherent X-ray illumination is required to image an object at high resolution.
