Changing the trajectory of Airy beam sets with spatial carriers
Компьютерная 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 ...

Curved plasma channels: Kerr lens and Airy prism [PDF]
Journal of the European Optical Society-Rapid Publications, 2009 We analytically calculate the transverse energy fluxes that would be respectively induced in high-power Airy beams by the Kerr self-focusing and the Airy profile itself if they were the only active process. Under experimental conditions representative of

2010 URSI International Symposium on Electromagnetic Theory, 2010 The Airy beams are analyzed in order to provide a cogent physical explanation to their intriguing features which include weak diffraction, curved propagation trajectories in free-space, and self healing. The asymptotically exact analysis utilizes the method of uniform geometrical optics (UGO), and it is also verified via a uniform asymptotic evaluation

Circular Airy Beam Based on Bandpass Filter
IEEE Photonics Journal, 2020 A new type of circular Airy beams is demonstrated by using a bandpass filter, in order to enhance the field intensity at the focal point of light beam, based on the angular spectrum representation and the ray optics picture. The specific ring and the key

Plasmonic Metalens to Generate an Airy Beam
Nanomaterials, 2023 Airy beams represent an important type of non-diffracting beams—they are the only non-diffracting wave in one dimension, and thus they can be produced with a cylindrical geometry that modifies a wavefront in one dimension.
