Generation of electron Airy beams [PDF]
Nature, 2013 Within the framework of quantum mechanics, a unique particle wave packet exists in the form of the Airy function. Its counterintuitive properties are revealed as it propagates in time or space: the quantum probability wave packet preserves its shape despite dispersion or diffraction and propagates along a parabolic caustic trajectory, even though no ...

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.

Optics Letters, 2014 In this Letter a new class of light beam arisen from the symmetrization of the spectral cubic phase of an Airy beam is presented. The symmetric Airy beam exhibits peculiar features. It propagates at initial stages with a single central lobe that autofocuses and then collapses immediately behind the autofocus. Then, the beam splits into two specular off-

Experimental investigation in Airy transform of Gaussian beams with optical vortex
Results 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.

Airy Transform of the New Power-Exponent-Phase Vortex Beam
Photonics, 2023 A new power-exponent-phase vortex beam with nonlinear phase winding has shown flexible control freedom compared with conventional vortex beams. In order to further enrich the modulation freedom and expand the ability of self-healing to meet current ...

Goos–Hänchen and Imbert–Fedorov shifts of the Airy beam in dirac metamaterials
New Journal of Physics, 2023 We theoretically derive the expression for the Goos–Hänchen (GH) and Imbert–Fedorov (IF) shifts of the Airy beam in Dirac metamaterial. In this work, the large GH and IF shifts can be found when the Airy beam is reflected near the Dirac and Brewster ...

Deep Penetration Microscopic Imaging with Non-Diffracting Airy Beams
Membranes, 2021 We report a deep penetration microscopic imaging method with a non-diffracting Airy beam. The direct mapping of volume imaging in free space shows that the axial imaging range of the Airy beam is approximately 4 times that of the traditional Gaussian ...
