Pyroelectrically induced photorefractive effect in Sr(0.61) Ba(0.39)Nb(2)O(6):Ce.
Photorefractive properties of a cerium-doped strontium barium niobate single crystal (Sr(0.61)Ba(0.39)Nb(2)O(6)) are investigated with Q-switched light pulses (wavelength 532 nm). Pyroelectric fields are the dominant charge driving force and significantly enhance light-induced refractive-index changes.
