| 摘 要： | 基于双光束耦合的原理及实验结果，计算了纯ＬｉＮｂＯ３和Ｆｅ：ＬｉＮｂＯ３晶体中的有效载流子密度，对结果进行了讨论，指出光折变ＬｉＮｂＯ３中氧空位色心也是载流子施主之一，且被激发的Ｆｅ２＋仅占晶体中Ｆｅ２＋浓度的一小部分。

| Abstract: | Based on the principles and experimental results of two-beam coupling,theeffective carrier density in pure LiNbO3 and Fe: LiNbO3 crystals has been calculated.Theresult is discussed and it is proposed that oxygen vacancy color center is one of the donors inphotorefractive LiNbO3 crystals and the stimulated Fe2 is a very small part of the Fe2 in thecrystal. |
