Research output: Contribution to journalConference articlepeer-review


We have determined the effective density of deep photorefractive centers and the effective electro-optic coefficient by measuring two-wave mixing gains in a Ce:Pb0.5Ba0.5Nb2O6 photorefractive crystal and compared with those of PBN. We have also investigated the light-induced absorption through pump-probe measurements at relatively low optical power densities. The density of shallow trap centers and their properties are studied from the buildup and decay of the light-induced absorption and its dependence on light intensity and temperature. Two-center model is applied to explain the experimental results.
