The photorefractive properties of 0.62Pb(Mg1∕3Nb2∕3)O3–0.38PbTiO3 single crystals have been investigated by the two-wave mixing experiment. The maximal gain coefficient is 5.4cm−1, the effective trap density is 1.2×1016cm−3, and the normalized photorefractive response time under 1W∕cm2 illumination is 1.5s at a wavelength of 632.8nm. The dominant charge carrier was identified as holes from the direction of two-wave mixing energy transfer.
