Abstract

Photorefractive properties of 0.88Pb(Zn_1/3Nb_2/3)O₃-0.12PbTiO₃ single crystal were investigated by the two-wave coupling experiment. The maximal gain coefficient is 5.5cm^-1, the effective trap density is 1.21 × 10¹⁶cm^-3, and the normalized photorefractive response time under 1W/cm² illumination is 1.48s at the wavelength of He-Ne laser. The dominant charge carrier was identified as electron from the direction of two-wave coupling energy transfer.
