| 摘 要： | 在ＬｉＮｂＯ３晶体掺入Ｔｂ离子，可提高晶体的光折变响应速度。Ｔｂ：Ｆｅ：ＬｉＮｂＯ３晶体既保留了Ｆｅ：ＬｉＮｂＯ３良好的光折变性能，同时其光折变响应时间大大缩短，可达十几秒，光折变响应速度的提高。可归结为晶光电导的增大，使得晶体内空间电荷场的建立更加迅速。

| Abstract: | The photorefractive response speed of LiNbO_3 crystal can be increased by doping with Tb ions.Su-perior photorefractive properties of Tb:Fe:LiNbO_3 will not only remained as Fe:LiNbO_3,but also its responsetime will be shortened greatly. This is due to the building of space charge field in the crystal more rapidly,as thephotoconductance increases. |
