文摘We report experimental studies on the photorefractive response of KNbO_(3) doubly doped with manganese and rubidium,iron and rubidium,respectively.Two-beam coupling response time in KNbO_(3):Mn:Rb is 3 to 10 times shorter while the two-beam coupling gain coefficient remains almost the same when compare with that in KNbO_(3):Mn.On the other hand,under similar conditions,two-beam coupling response time in KNbO_(3):Fe:Rb is 6 times faster than that in KNbO_(3):Fe.
