In this paper, a new kind of photorefractive Cu:KNSBN crystal with Li-replacement at A-sites ((Cu,Li):KNSBN) was reported. We studied the photorefractive properties of this kind of crystal by using the conventional two-wave mixing method. It revealed that the Li-replacement can improve the photorefractive response rate of the crystal which is very important in real time information processing. An response time of 90 ms was obtained at a total incident intensity of 3.92 W/cm2. The absorption spectrum and other photorefractive properties were also measured and discussed. Experiment showed that cation replacement such as Li- replacing at A-sites provides a new way to improve the photorefractive properties of KNSBN crystals.
