The Airy beam also has the characteristic of freely accelerating.

An Airy beam is a non-diffracting waveform which gives the appearance of curving as it travels.

Georgios Sivilioglou, et al. successfully fabricated an Airy beam in 2007.

Researchers at the University of St. Andrews have used Airy beams to manipulate small particles, moving them along curves and around corners.

I gaze at the dome above me, which is pierced by holes, and am transfixed by the airy beams of pastel light that flow through it.

A cross section of an Airy beam would reveal an area of principal intensity, with a series of adjacent, less luminous areas trailing off to infinity.

However, in two dimensions (or 3D paraxial systems), two separable solutions are possible: two-dimensional Airy beams and accelerating parabolic beams.

In one-dimension, the Airy beam is the only exactly shape-preserving accelerating solution to the free-particle Schrödinger equation (or 2D paraxial wave equation).

In 2007 researchers from the University of Central Florida were able to create and observe an Airy beam for the first time in both one- and two-dimensional configurations.

The term "Airy beam" derives from the Airy integral, developed in the 1830s by Sir George Biddell Airy to explain optical caustics such as those appearing in a rainbow.
