摘 要: | 在LiNbO3晶体中掺入ZnO,生长ZnO:LiNbO3晶体,当ZnO的掺入浓度高于6mol%时,晶体的抗光损伤能力提高两个数量级,与高掺Mgo相似。Zn:LiNbO3的倍频转换效率可达50%左右,高于Mg;LiNbO3。本文对Zn:LiNbO3晶体中Zn^2+离子占痊以及抗光损伤增强机理进行了初步探讨。

Abstract: | Doping ZnO into LiNbO3, Zn:LiNbO3 crystal have been grown. The photo damage resistance increases of two magnituder when the ZnO doping concentrations were higher than 6 mol%. This value is similar to that of MgO(>4.6 mol%):LiNbO 3. The frequency doubling conversion efficiency of Zn (6 mol%):LiNbO3 was measured to be about 5%, ligher than that of Mg (6 mol%):LiNbO3. The location of Zn2+ ions and the enhancement machenism of photo damage resistance of Zn:LiNbO3 are discussed in this paper. |
