Observation of Accelerating Airy Beams


Observation of Accelerating Airy Beams

G A Siviloglou et al. Phys Rev Lett. .


We 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 distances while they tend to freely accelerate during propagation.
