Abstract
The photorefractive properties of Mn-doped KNSBN crystals, especially the crystal with a higher doping level (0.09 wt.%), was studied. Experiments showed that the properties of Mn:KNSBN crystals with 0.09 wt.% are different from others. This maybe provides a good material to study the electron-hole competition, which exists widely in PR crystals. The high order harmonic properties were also investigated. Five orders of harmonics were observed. It was found that the maximum of the second order index grating shifts towards a smaller incident angle with respect to that of the fundamental grating. Based on the strong harmonics in this kind of crystals, the recording of harmonic index gratings was achieved by using a novel method in experiment.
