Abstract
The beam coupling and response time of reduced BaTiO3 are reported. Th e major carrier changes from hole to electron after reduction. The ele ctro-optic gain and effective trap density increase with the illuminat ion intensity. Although the electro-optic gain varies little, the resp onse time tau decreases by a factor of 2.8 after reduction. Experiment al results indicate that at least three energy levels including shallo w level(s) exist in this BaTi0(3).
