Abstract

Zinc doping is shown to reduce the photorefraction in LiNbO(3):Zn. The damage-resistant crystal LiNbO(3):Zn has demonstrated a conversion efficiency of approximately 50% for frequency doubling of 1.06-microm radiation. The dependence of optical characteristics on the ZnO concentration in the melt reveals a sharp change of the optical properties at the threshold concentration of 4-6 mol % Zn. The optical and nonlinear-optical data of LiNbO(3):Zn are similar to those of LiNbO(3):Mg, but the former shows better optical performance.

摘要

已表明锌掺杂可降低铌酸锂（LiNbO₃）:Zn中的光折变效应。抗损伤晶体LiNbO₃:Zn在1.06微米辐射倍频方面已展现出约50%的转换效率。光学特性对熔体中ZnO浓度的依赖性表明，在4 - 6摩尔% Zn的阈值浓度下光学性质会发生急剧变化。LiNbO₃:Zn的光学和非线性光学数据与LiNbO₃:Mg的相似，但前者表现出更好的光学性能。
