Paper Abstract

We report our experimental studies on the photorefractive response of KNbO3 double doped with manganese and rubidium. Two-beam coupling response time of photorefractive potassium niobate crystals is 3 to 10 times improved by double doping manganese and rubidium, when compared with that of the KNbO3:Mn crystals, which have shown a strong photorefraction. The photorefractive two-beam coupling gain coefficient in such crystals remains almost the same as those in KNbO3:Mn, which is 3 times higher than that of KNbO3 doped with rubidium alone, which has a fast response time.
