The photorefractive properties of Cu-doped crystals with different doping levels and different dimensions are investigated by using the conventional two-wave mixing approach. Reports show that Li-replacement at A-sites further improves the photorefractive properties of KNSBN crystals. The doped crystals exhibit good properties like higher coupling coefficient, higher self pump phase conjugation reflectivity and relatively stable photorefractive properties.
