Photorefractive properties of 0.88Pb(Zn1/3Nb2/3)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.
