It is demonstrated that Er doping increases the photorefractive effect in LiTaO3. Raman and fluorescence spectra are used to establish that the upconverted green emission of Er3+ clusters acts as a gating source, significantly increasing the two-photon photorefractive effect of a monochromatic red or near-infrared pump source.
