摘要
在Ｆｅ∶ＬｉＮｂＯ＿３晶体中掺入Ｓｍ＿２Ｏ＿３，生长出Ｓｍ、Ｆｅ双掺杂晶体Ｓｍ∶Ｆｅ∶ＬｉＮｂＯ＿３，在Ｈｅ－Ｎｅ激光下，分别用二波和四波混频方法测试了Ｓｍ∶Ｆｅ∶ＬｉＮｂＯ＿３的指数增益系数，衍射效率和相位共轭反射率及其响应时间。与Ｆｅ∶ＬｉＮｂＯ＿３相比，Ｓｍ∶Ｆｅ∶ＬｉＮｂＯ＿３的响应时间大大缩短。
Doping Sm_2O_3 to Fe∶LiNbO_3,the double-doped Sm∶Fe∶LiNbO_3 crystal has been grown. Using He-Ne laser,the exponential gain,the diffractive efficiency ,the phase conjugative reflectivity and the response time are measured by two-wave and four-wave couplin.Comparing to Fe∶ LiNbO_3.The response time of Sm∶Fe∶ LiNbO_3 is short of a lot.
