  This work presents, for the first time the optical generation of
non-diffracting beams via photorefractive holography. Optical generation of
non-diffracting beams using conventional optics components is difficult and, in
some instances, unfeasible, as it is wave fields given by superposition of
non-diffracting beams. It is known that computer generated holograms and
spatial light modulators (SLMs) successfully generate such beams. With
photorefractive holography technique, the hologram of a non-diffracting beam is
constructed (recorded) and reconstructed (reading) optically in a nonlinear
photorefractive medium. The experimental realization of a non-diffracting beam
was made in a photorefractive holography setup using a photorefractive
Bi12SiO20 (BSO) crystal as the holographic recording medium, where the
non-diffracting beams, the Bessel beam arrays and superposition of
co-propagating Bessel beams (Frozen Waves) were obtained experimentally. The
experimental results are in agreement with the theoretically predicted results,
presenting excellent prospects for implementation of this technique for
dynamical systems at applications in optics and photonics.
