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

Partially coherent Mathieu–Gauss beams [PDF]
Scientific ReportsWe 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 ...

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.

Generation and Propagation of Partially Coherent Power-Exponent-Phase Vortex Beam
Frontiers in Physics, 2021 We report on a partially coherent power-exponent-phase vortex beam (PC-PEPV), whose spatial coherence is controllable and the initial phase exhibits a periodic power exponential change.

Measurement of the coherence-orbital angular momentum matrix of a partially coherent beam.
Optics Letters, 2022 The recently introduced coherence-orbital angular momentum (COAM) matrix of a partially coherent beam [Phys. Rev. A103, 023529 (2021)10.1103/PhysRevA.103.023529] is experimentally measured for the first time, to the best of our knowledge.

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.
