Abstract

Tetragonal lead barium niobate (Pb1-xBaxNb2O6; 1 - x < 0.63) crystals are promising photorefractive materials for applications such as holographic data storage. Measurements of light-induced absorption in Ce-doped lead barium niobate (Pb0.5Ba0.5Nb2O6) were performed. The induced absorption that was due to the presence of shallow traps was as large as 0.3 cm-1 at 633 nm and exhibited saturation behavior at green-pump intensity greater than 2 W/cm2. The temporal profile of the dark decay was a double exponential, and the activation energies of the slow- and the fast-decaying components were determined to be 0.16 and 0.3 eV, respectively.
