以Na 2 O-B2 O3-NaF为助熔剂，采用顶部籽晶溶液法（TSSG）生长了30×20×8 mm 3 Na 3La 2（BO 3）3晶体。用最小偏差法精确测量了0.2537 ~ 2.325 μm范围内13个波长的折射率，并据此建立了Sellmeier方程。用Maker条纹法测量了样品的非线性光学系数，结果分别为d31 =1.45 pm/V，d32=0.67 pm/V，d33 =-1.06 pm/V。对于1064 nm的二次谐波，在相位匹配角θ=77.0°，θ =212.1°时，I型相位匹配的有效非线性光学系数（deff）达到最大值（1.44 pm/V），大于LiB 3 O 5（LBO）的有效非线性光学系数。第一性原理计算表明，Na 3La 2（BO 3）3具有两种NLO活性原子团：π轨道体系的BO 3基团和具有大极性位移的La心多面体，其中后者可视为一种新的NLO活性原子团.
A 30×20×8 mm3Na3La2(BO3)3crystal has been grown by the top-seeded solution growth method (TSSG) using Na2O–B2O3–NaF as flux. The refractive indices at thirteen wavelengths from 0.2537 to 2.325 μm were accurately measured by the minimum deviation method, and the Sellmeier equations were accordingly constructed. The nonlinear optical (NLO) coefficients were measured by the Maker fringe method, which gave results ofd31=1.45 pm/V,d32=0.67 pm/V, andd33=−1.06 pm/V, respectively. For second-harmonic generation (SHG) of 1064 nm, the effective NLO coefficient (deff) of type I phase-matching reaches the maximum value (1.44 pm/V) at the phase-matching anglesθ=77.0°,ϕ=212.1°, which is larger than that of LiB3O5(LBO). First-principle calculations suggest that Na3La2(BO3)3possesses two types of NLO-active atom groups, BO3group with π-orbital system and La-centered polyhedron with large polar displacement, of which the latter could be considered as a new type of NLO-active atom group.
