Temperature-dependent efficiency and speed of response of a Ce-doped barium titanate crystal as a self-pumped phase conjugator are investigated at 514.5 and 632.8 nm. It was observed that its efficiency and speed of response are improved at elevated temperature. Two-beam coupling measurements were also carried out at different temperatures, showing that the coupling gain coefficient as well as the corresponding speed of response of the crystal are also enhanced at elevated temperature. In addition to the photorefractive properties, the absorption coefficient of the crystal was also found to increase with temperature, implying that there are at least two deep-trap levels in the crystal.
