Sm:Fe:LiNbO3 crystal was grown by doping Sm2O3 in Fe:LiNbO3 crystal. The exponential gain coefficient; diffraction efficiency and photorefractive response time were measured by two-wave mixing experiment; respectively. It was found that the response speed was greatly improved by doping Sm ions in Fe:LiNbO3 crystal. Our analysis also showed that photoconductivity enhancement was responsible for improving the response speed in the Sm:Fe:LiNbO3 crystal. © 2006 Elsevier B.V. All rights reserved;
