摘要: 用干涉仪的方法测量了Ce:BaTiO3晶体的低频电光系数和压电系数．排除压电效应对光通过晶体引起相位的变化，得到低频下经极化的Ce:BaTiO3单晶的电光系数r42=1945±220pm/V和r13=11.8±1pm/V．从而，为研究Ce:BaTiO3晶体的光折变效应和理论计算提供了精确的线性电光系数

Abstract: We have measured,for the first time,the low frequency (unclamped)electro-optic and piezoelectric coefficients in Ce:BaTiO3 crystals using interferometric techniques.When the piezoelectric contribution to the phase change by a beam passing through the crystals is ruled out,the unclamped electro-optic coefficients of the poled Ce:BaTiO3 single crystals are r42=1945±220pm/V and r13=11.8±1pm/V.Consequently,accurate values of the Pockels coefficients are provided for researching the photorefractive effect and theoretical study of the Ce:BaTiO3 crystal.
