Abstract

Two-step two-color recording is demonstrated in a photorefractive La3Ga5SiO14:Pr3+ crystal using cw laser radiation. The 488 nm line from an Ar-ion laser is used for gating and gratings are written using a Ti:sapphire laser operating in the range from 788 to 840 nm. The dependence of holographic recording on grating and writing intensity is investigated. A saturation of the sensitivity is found for 2 W/cm(2) of grating intensity. A threshold photon energy of 1.53 eV for the second excitation step is observed. (C) 1999 American Institute of Physics.
