掺镁的铌酸锂晶体 |
不同掺杂的准化学 计量比铌酸锂晶体 |
利用人工准晶实现的 二倍频及三倍频 |
铌酸锂LiNbO3）晶体被广泛用作1000nm以上波长的倍频和1064nm泵浦光的光参量放大,也可做准相位匹配. 但是，应用LiNbO3晶体对Nd:YAG激光进行倍频时，由于光折变效应的存在，大大降低了它的抗光伤阈值。高掺杂MgO（MgO掺杂浓度大于5mol%）铌酸锂晶体与纯铌酸锂晶体相比，其抗光损伤能力提高两个数量级。同时,铌酸锂晶体也被广泛应用于光电调节器及波导材料,和用作Nd:YAG,Nd:YLF和掺Ti的蓝宝石激光Q开关. Terahertzlabs可为上述用途提供各种规格的高质量,大尺寸的铌酸锂晶体. 掺杂铁后的铌酸锂晶体，其光折变性能比纯铌酸锂提高500倍，并能储存多个全息图，从而成为一种重要的激光全息照相用记录材料；

Magnesium Oxide Doped Lithium Niobate Crystal
Compared with LiNbO3 crystal, MgO:LiNbO3 crystal exhibits its particular advantages for NCPM
frequency doubling (SHG) of Nd:Lasers, mixing (SFG) and optical parametric oscillators
(OPOs). MgO:LiNbO3 is also a good crystal for optical parametric oscillators (OPOs) and
amplifiers (OPAs), quasi-phase-matched doublers and integrated waveguide.
MgO:LiNbO3 has similar effective nonlinear coefficients to pure LiNbO3 . Its Sellmeier equations
(for MgO dopant 7 mol%) are:
no2=4.8762+0.11554/(λ2 - 0.04674) - 0.033119λ2
ne2=4.5469+0.094779/(λ2 - 0.04439) - 0.026721λ2
