A method to design lasers that emit an arbitrary beam profile is studied. In these lasers, output-coupling is
performed by a diffraction grating that imposes a phase and amplitude distribution onto the diffracted light. A
solid-state laser emitting beams with a two-dimensional Airy intensity profile is demonstrated both theoretically
and experimentally. In this case, the diffraction grating adds a transverse cubic phase to the diffracted light. An Airy
beam is obtained by performing optical Fourier transform of the out-coupled light. The laser beam profile and power
characteristics are shown to agree with theory. 2011 Optical Society of America

Airy beams are optical beams whose profile is described
bythe Airy function [1,2].These beamspossess several un-
ique features, such as propagation along a curved trajec-
tory, very low diffraction [1,2], and self-healing, i.e., they
restore their canonical form after passing small obstacles
[3]. Applications of Airy beams include plasma waveguid-
ing [4], microparticle manipulation [5], generation of light
