Finite-energy Airy beams were first introduced in the field of optics in 2007 (refs 1, 2) as new non-diffracting wavepackets in one and two spatial dimensions. The Airy function, describing the ...
The demonstration of Airy beam generation and all-optical control by quasi-phase matched nonlinear crystals looks set to help these unique beams realize their exciting potential in applications. In ...
