中文摘要：

采用顶部籽晶法生长出掺杂浓度为3％的Nd：Na3La9O3（B03）8（Nd：NLBO）晶体。X射线粉末衍射图表明Nd：NLBO与NLBO的晶体结构相同，属于六方晶系。Nd：NLBO（3％）晶体的分凝系数为1．05。测试了晶体的吸收光谱，Nd：NLBO晶体在804nm有较强的吸收，吸收截面为3．2×10^20cm^2，半宽度为6．3nm。Nd：NLBO可能是一种潜在的自倍频晶体。

英文摘要：

A new Nd-activated nonlinear crystal, Na3 （La1-xNdx）9O3（BO3）s（Nd：NLBO）with x = 3%, was grown by the top-seeded solution growth （TSSG） method. XRD pattern revealed the crystal structure of Nd：NLBO was the same as the NLBO crystal. The segregation coefficient of Nd ： NLBO （3%） was calculated to be 1.05. The absorption spectrum of the crystal were measured. The results showed that Nd：NLBO had a strong absorption band at 804 nm, the absorption cross-sections was 3.2 × 10^-20 cm^2, and the full- width at half-maximum （FWHM） was 6.3 nm. Nd ： NLBO may be a potential self-frequency doubling （SFD） crystal.
