Abstract

We report what we believe to be the first observation of photorefractive gratings in lead barium niobate (Pb^1-x;Ba_xNb₂O₆; PBN). A diffraction efficiency of 9% and a beam-coupling coefficient of 9 cm^-1 are obtained. After thermal fixing a grating of 0.5% is revealed at room temperature. We can improve this diffraction efficiency by optimizing fixing temperature, timing, and material parameters.
