Abstract

We investigate a novel single doping photorefractive material, Ru doped lithium niobate, which offers photochromism for nonvolatile holographic storage. Ru:LiNbO3 crystals doped with different Ru concentrations from congruent composition melts were grown by the Czochralski method [1]. The color of the Ru:LiNbO3 was red and darkened as the Ru concentration increased. However, the Ru:LiNbO3 crystals have solubility limit, so the maximum amount of Ru that can be doped into LiNbO3 single crystals is about 0.2 mol%.
