Experimental investigation in Airy transform of Gaussian beams with optical vortex

open access: yesResults in Physics, 2021
The Airy transform was first introduced for a Gaussian beam, and the output beam is an Airy beam. When the Gaussian beam is extended to the Gaussian beam with optical vortex, what kind of output beam will be achieved by executing the Airy transformation.

Terawatt-Class Few-Cycle Short-Wave Infrared Vortex Laser

open access: yesUltrafast Science, 2023
As a driving source for many nonlinear vortex phenomena, such as the generation of isolated attosecond optical vortices, terahertz vortices, etc., terawatt-class few-cycle short-wave infrared vortex lasers are now attracting widespread attention. However,

Entangled Optical Vortex Links [PDF]

open access: yesPhysical Review Letters, 2011
Optical vortices are lines of phase singularity which percolate through all optical fields. We report the entanglement of linked optical vortex loops in the light produced by spontaneous parametric down-conversion. As measured by using a Bell inequality, this entanglement between topological features extends over macroscopic and finite volumes.

Optical Vortex Brillouin Laser

open access: yesLaser & Photonics Reviews, 2023
AbstractOptical vortices, which have been extensively studied over the last decades, offer an additional degree of freedom useful in many applications, such as optical tweezers and quantum control. Stimulated Brillouin scattering (SBS), providing a narrow linewidth and a strong nonlinear response, has been used to realize quasi‐continuous wave lasers ...

Real-time phase measurement of optical vortex via digital holography

open access: yesFrontiers in Physics, 2023
Real-time phase measurement is of great value to study the evolution of optical vortex. However, it cannot be recorded in real time due to the limitation of the exposure time of the recording device in the experiment. Therefore, based on the temporal and

Abrupt autofocusing performance of a circular Airyprime beam with vortex pairs

open access: yesResults in Physics, 2023
Abrupt autofocusing performance of a circular Airyprime beam (CAPB) with vortex pairs propagating in free space is investigated. Here the vortex pairs are off-axis by default.

Collapse Dynamics of Vortex Beams in a Kerr Medium with Refractive Index Modulation and PT-Symmetric Lattices

open access: yesPhotonics, 2022
Using the two-dimensional nonlinear Schrödinger equation, the collapse dynamics of vortex beams in a Kerr medium with refractive index modulation and parity–time (PT) symmetric lattices are explored. The critical power for the collapse of vortex beams in
