| Abstract: | Doping 3mol% and 6mol% MgO in Fe:LiNbO3,Mg:Fe:LiNbO3 crystals were grown.The photo scattering resistance ability,diffraction efficiency,response time and photoconduction of Mg:Fe:LiNbO3 were measured.The response time dependence on the photo conduction was deduced.The photo scattering resistance ability of Mg(6mol%):Fe:LiNbO3 is one order of magnitude higher than that of Fe:LiNbO3 and the response rate of Mg(6mol%):Fe:LiNbO3 is four times faster than that of Fe:LiNbO3. |
