Highly-accurate manipulation of focal length for circular Airy beams
npj NanophotonicsThe existing excitation models for circular Airy beams suffer from focal length deviation, which reduces the positioning accuracy of the focal point.

Dynamic Control of Circular Airy Beams With Linear Optical Potentials
IEEE Photonics Journal, 2012 We investigate the propagation dynamics of radially symmetric, circular Airy beams through a medium having linear optical potentials. On the basis of analytic expressions and numerical calculations, we show that “off-axis” autofocusing can ...

Airy wavepackets are Perelomov coherent states
, 2018 Accelerating non-spreading wavepackets in nonrelativistic free particle system, with probability distribution having an Airy function profile, were discovered by Berry and Balazs (1979), and have been subsequently realised in several optical experiments.

Advanced Engineering Materials, EarlyView.Cermets (60 vol.% AISI 316L stainless steel, 40 vol.% recycled MgO), intended for use in aluminum electrolysis, were pre‐oxidized in three furnaces with different heating technologies and subjected to a cryolite corrosion test. The different atmospheres influenced the formation of oxide layers, which in turn affected corrosion resistance and ...

Advanced trajectory engineering of diffraction-resisting laser beams [PDF]
, 2013 We introduce an analytical technique for engineering the trajectory of diffraction-resisting laser beams. The generated beams have a Bessel-like transverse field distribution and can be navigated along rather arbitrary curved paths in free space, thus ...

Closed-form expressions for nonparaxial accelerating beams with pre-engineered trajectories
, 2015 In this letter, we propose a general real-space method for the generation of nonparaxial accelerating beams with arbitrary predefined convex trajectories. Our results lead to closed-form expressions for the required phase at the input plane.

The Quadruple Gaussian Airy Beam and Its Propagation Properties
PhotonicsIn recent years, structured light with novel propagation properties has attracted great attention. Among these structured beams, the Airy beam is one of the most representative and widely used beams. In this paper, we propose a kind of quadruple Gaussian
