Generation of Hollow Airy Beam by Superposing of Two-Dimensional Airy Beams [PDF]
, 2022 Abstract We study the collisions of four self-focused counterpropagating 2D Airy beams propagating in free space. Their interactions demonstrate that can be obtained hollow beams through the superposition of more than two Airy beams and are well-preserved upon propagation.

Dynamic Control of Airy Beams Using Real-Time Phase-Amplitude Encoding on a Spatial Light Modulator
OpticsAiry beams showing curved paths have found extensive applications in fields such as optical trapping, biomedical analysis, and material processing. Despite their utility, dynamic control of Airy beams poses a significant challenge. This work investigates

Propagation-invariant vortex Airy beam whose singular point follows its main lobe
New Journal of Physics, 2021 We propose and demonstrate a novel vortex Airy beam which is a superposition of an Airy beam and its laterally sheared beam with a π /2 phase shift.

Generation and characteristics of an Airy vortex beam from the anomalous vortex beam
Results in Physics, 2022 Hybrid beams have evoked a long-running research upsurge due to its unique properties and extensive application. In this paper, we propose a novel method to generate a kind of hybrid Airy vortex beam (AiVB) with orbital angular momentum (OAM) by imposing

Optics Letters, 2011 The phase behavior of Airy beams is studied, and their Gouy phase is defined. Analytic expressions for the idealized, infinite-energy type beam are derived. They are shown to be excellent approximations for finite-energy beams generated under typical experimental conditions.

Generation of Talbot-like fields
Scientific Reports, 2021 We present an integral of diffraction based on particular eigenfunctions of the Laplacian in two dimensions. We show how to propagate some fields, in particular a Bessel field, a superposition of Airy beams, both over the square root of the radial ...

Design, transform and control of optical field in discrete optical system: an example
Scientific Reports, 2017 A discrete optical system can broaden the spatial distribution of the input light through optical coupling in array waveguides, just like diffraction in continuous media.

Intensity-symmetric Airy beams
Journal of the Optical Society of America A, 2015 Theoretical, numerical, and experimental research on a novel family of Airy beams in rectangular coordinates having a symmetric transverse pattern of light intensity is presented. The intensity-symmetric Airy beams include both the symmetric Airy beam whose field amplitude is an even function of the transverse coordinates and the antisymmetric Airy ...

FEBS Open Bio, EarlyView.Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...
