Abstract

Magnesium1-3, zinc4-6 and some other impurities (substituting mainly for the lithium sites) drastically change optical properties of LiNbO3. In particular the value of optical damage (photorefraction) in LiNbO3:Me (Me = Mg,Zn,…) is sharply reduced compared with undoped LiNbO32-6. Similarly Me impurities tend to supress so-called "dark trace” effect4-6 (that means stable darkening under intensive visible laser radiation).

铌酸锂中抗光学损伤杂质

镁- 1-3、锌- 4-6和其他一些杂质(主要取代锂位)极大地改变了LiNbO3的光学性质。特别是与未掺杂的LiNbO32-6相比，LiNbO3:Me (Me = Mg,Zn，…)中的光学损伤值(光折射率)明显降低。同样，Me杂质也会抑制所谓的“暗迹”效应4-6(即在强烈的可见激光辐射下稳定变暗)。
