Abstract
We focus on a photorefractive response under the influence of temperature in conjunction with reduction. A series of reduced BaTiO3:Rh crystals is made. Their optical absorptions, dark decays, and light-induced decays are investigated. The temperature-dependent dark decay and light-induced decay are performed by an argon ion laser operated at 514.5 nm. The experimental results show that the photorefractive response can be improved by reduction in cooperation with the elevation of temperature. For different types of Rh-doped barium titanate crystals, the elevation of temperature has different influences in their photorefractive responses. The sample reduced at 10–14 atm has the best response of 15 ms at 100°C.
