  In this paper, we present the experimental generation of Airy beams via
computational and photorefractive holography. Experimental generation of Airy
beams using conventional optical components presents several difficulties and
are practically infeasible. Thus, the optical generation of Airy beams has been
made from the optical reconstruction of a computer generated hologram
implemented in a spatial light modulators. In the photorefractive holography
technique, being used for the first time to our knowledge, the hologram of an
Airy beam is constructed (recorded) and reconstructed (reading) optically in a
nonlinear photorefractive medium. The Airy beam experimental realization was
made by a setup of computational and photorefractive holography using a
photorefractive Bi_{12}TiO_{20} crystal as holographic recording medium. Airy
beams and Airy beam arrays were obtained experimentally as in accordance with
the predicted theory; and present excellent prospects for applications in
optical trapping and optical communications systems.
