Abstract: 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 distance. The Airy beams of the second kind can be generated near a phase transparency with cubic phase modulation.

Observation of accelerating Airy beams.
TL;DR: In this paper, the first observation of Airy optical beams has been reported in both one-and two-dimensional configurations, and they exhibit unusual features such as the ability to remain diffraction-free over long distances while they tend to freely accelerate during propagation.

Accelerating finite energy Airy beams
TL;DR: This work investigates the acceleration dynamics of quasi-diffraction-free Airy beams in both one- and two-dimensional configurations and shows that this class of finite energy waves can retain their intensity features over several diffraction lengths.

TL;DR: In this article, it was shown that for a wave ψ in the form of an Airy function the probability density ψ 2 propagates in free space without distortion and with constant acceleration.

Nondiffracting accelerating wave packets of Maxwell's equations.
TL;DR: In this paper, the authors present the non-iffracting spatially accelerating solutions of the Maxwell equations, which accelerate in a circular trajectory, thus generalizing the concept of Airy beams to the full domain of the wave equation.

Accelerating Light Beams along Arbitrary Convex Trajectories
TL;DR: It is found that all nonbroadening optical beams, accelerating along any convex trajectory, display the same universal intensity cross section, irrespective of their acceleration.
