title: Two-photon recording of microholograms in undoped lithium tantalate.
abstract: Two-photon recording of microholograms was demonstrated in undoped congruent lithium tantalate crystal with high holographic sensitivity, large refractive index change, and fast hologram writing time. Nonvolatile heterodyne readout was carried out at a wavelength of 660 nm. Recording of a 3 x 3 x 3 matrix of microholograms was realized and it showed the cross-talk effect was negligibly small.
