摘　　要：用提拉法从熔体中生长了 Ｃｅ：Ｆｅ：ＬｉＮｂＯ３晶体．研究了 Ｃｅ：Ｆｅ：ＬｉＮｂＯ３晶体在 ６３３ｎｍ波段的体全息存储特性，对不同掺杂浓度的 Ｃｅ：Ｆｅ：ＬｉＮｂＯ３和Ｆｅ：ＬｉＮｂＯ３晶体进行了全息时间常数和吸收光谱的测定与比较．实验表明，Ｃｅ：Ｆｅ：ＬｉＮｂＯ３晶体对红光的灵敏度优于Ｆｅ：ＬｉＮｂＯ３晶体，它是一种优良的体全息记录材料．Crystals of Ce: Fe: LINbO3 were grown from melt by Czochraski method. Compact Volume Holographic storage properties of the Ce: Fe: LiNbO3 at 633 nm have been studied for the first time. The response time of Fe: LiNbO3 and Ce: Fe: LiNbO3, with different impurity density, has been measured and compared. It is shown in our experment that Ce: fo: LINbO3 crystal is more sensitive to 633 urn than Fe:LINbO3 crystal. So it is a good kind of material of Volume Holographic record.
