Airy-beam tomographic microscopy

open access: yesOptica, 2020
We introduce Airy-beam tomographic microscopy (ATM) for high-resolution, volumetric, inertia-free imaging of biological specimens. The work exploits the highly adjustable Airy trajectories in the 3D space, transforming the conventional telecentric wide-field imaging scheme that requires sample or focal-plane scanning to acquire 3D information.

Generation of electron Airy beams [PDF]

open access: yesNature, 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 ...

Dual Airy beam

open access: yesOptics Express, 2010
We derive a general form of Airy wave function which satisfies paraxial equation of diffraction. Based on this, we propose a new form of Airy beam, which is composed of two symmetrical Airy beams which accelerate mutually in the opposite directions. This 'dual' Airy beam shows several distinguishing features: it has a symmetric transverse intensity ...

Generation and Manipulation of Airy Breathing Solitons in an Inhomogeneous Medium with Periodic Potential

open access: yesPhotonics, 2023
The propagation characteristics of Airy beams in an inhomogeneous medium with periodic potential are studied theoretically and numerically. The Gross–Pitaevskii equation was solved with periodic potential using the separating variables method, and a ...

Airy-Gauss beams and their transformation by paraxial optical systems [PDF]

open access: yes, 2007
We introduce the generalized Airy-Gauss (AiG) beams and analyze their propagation through optical systems described by ABCD matrices with complex elements in general. The transverse mathematical structure of the AiG beams is form-invariant under paraxial

Changing the trajectory of Airy beam sets with spatial carriers

open access: yesКомпьютерная оптика, 2022
In this paper, we study a change in the propagation trajectory of a set of autofocusing laser beams using a fractional Fourier transform. Clusters of displaced bounded Airy-Gaussian beams supplemented by a phase function that deflects the beam similarly ...

Super-Airy beams

open access: yesOptics Express, 2023
We report on the numerical simulation results of the propagation of Fourier-transformed super-Gaussian beams with cubic phase modulation, which we refer to as super-Airy beams. We show the effect of the truncation profile on the propagation of the "Airy" intensity distribution and propose methods to improve the non-diffracting propagation length.

Observation of accelerating parabolic beams [PDF]

open access: yes, 2008
We report the first observation of accelerating parabolic beams. These accelerating parabolic beams are similar to the Airy beams because they exhibit the unusual ability to remain diffraction-free while having a quadratic transverse shift during ...

Reflection and refraction of an Airy beam at a dielectric interface [PDF]

open access: yes, 2012
Reflection and refraction of a finite-power Airy beam at the interface between two dielectric media are investigated analytically and numerically. The formulation takes into account the paraxial nature of the optical beams to derive convenient field ...
