A finite-energy bending Airy beam solution to the paraxial equation in free space was first formulated analytically by Siviloglou and Christodoulides and subsequently demonstrated experimentally by Siviloglou, Broky, Dogariu and Christodoulides. This work was motivated by the infinite-energy (nonspreading) accelerating Airy solution to the Schrudinger ...

Radially polarized symmetric Airy beam
Optics Letters, 2020In this Letter, we introduce a new kind of radially polarized beam called the radially polarized symmetric Airy beam (RPSAB). Compared to the linearly polarized symmetric Airy beam (SAB), the hollow focus spot of RPSAB enables it to trap a microparticle whose refractive index is lower than that of the surrounding medium, and the focus intensity of ...

We discuss finite-energy and infinite-energy Airy beams of the second kind. Similarly to the well-known paraxial Airy beams, these are accelerating beams that can be analytically described in the Fresnel diffraction zone but propagate along a hyperbolic rather than parabolic path over a certain length, with their “gravity center” shifting linearly with

Airy beams are of great interest as a result of their unusual characteristics, they are non-diffracting and also propagate along a parabolic path due to the presence of a transversal acceleration component. In this paper the generation of a white light Airy beam is presented, an investigation is also carried out to determine how the properties of an

Abstract Acoustic Airy beams as non-diffractive beams possess self-bending, self-healing, and non-diffraction virtues and are expected to have great potential in applications like ultrasonic imaging. Here an analytical theory is provided for Gaussian modulated Airy (gAiry) acoustic beams. It is revealed through numerical calculations and

Observation of Accelerating Airy Beams
Frontiers in Optics 2007/Laser Science XXIII/Organic Materials and Devices for Displays and Energy Conversion, 2007We report the first observation of Airy optical beams. This intriguing class of wave packets, initially predicted by Berry and Balazs in 1979, has been realized in both one- and two-dimensional configurations. As demonstrated in our experiments, these Airy beams can exhibit unusual features such as the ability to remain diffraction-free over long ...

Accelerating finite energy Airy beams
Optics Letters, 2007We investigate the acceleration dynamics of quasi-diffraction-free Airy beams in both one- and two-dimensional configurations. We show that this class of finite energy waves can retain their intensity features over several diffraction lengths. The possibility of other physical realizations involving spatiotemporal Airy wave packets is also considered.

Ballistic dynamics of Airy beams
Optics Letters, 2008We demonstrate both theoretically and experimentally that optical Airy beams propagating in free space can perform ballistic dynamics akin to those of projectiles moving under the action of gravity. The parabolic trajectories of these beams as well as the motion of their center of gravity were observed in good agreement with theory.

Switchable Second‐Harmonic Generation of Airy Beam and Airy Vortex Beam
Advanced Optical Materials, 2020AbstractAiry beam and Airy vortex beam with intriguing characteristics have been extensively studied in linear optics, while their dynamic nonlinear conversion has rarely been explored and remains challenging. Here, through the collaboration of binary mask engineered nonlinear photonic crystal and space‐variant liquid‐crystal geometric phase element ...

Wave analysis of Airy beams and Airy Pulsed Beams
2013The Airy beam (AiB) has attracted a lot of attention recently because of its intriguing features. We have previously provided a cogent physical explanation for these properties by showing that the AiB is, in fact, a caustic of rays that radiate from the tail of the Airy function aperture distribution. We have also introduced a class of ultra wide band (
