单斜BiB 3 O 6（以下简称BIBO）（空间群C2 [1]）已从化学计量熔体中生长出光学质量尺寸高达5 × 4 × 2厘米的单晶。我们已经确定了基波λ（0）= 1079.5nm的二次谐波产生d（ijk）（SHG）的所有独立非线性光学（nlo）系数。在单斜或较低对称性的晶体中，d（ijk）（SHG）张量的完全确定，据我们所知还没有发表。线性光学研究表明，相位匹配过程的波长范围很宽，我们发现在1079.5 nm处沿着二次谐波产生的相位匹配方向的最高d（eff）为3.2 pm/V。这个值大于许多其他物质，如KTiOPO_4（KTP）或β-BaB_2 O_4（BBO），在应用中被广泛使用。(C)1998爱思唯尔科技有限公司版权所有。
The monoclinic BiB3O6 (abbreviation BIBO hereafter) (space group C2 [1]) has been grown from stoichiometric melts in single crystals of dimensions up to 5 x 4 x 2 centimeters in optical quality. We have determined all independent nonlinear optical (nlo) coefficients of second harmonic generation d(ijk)(SHG) for the fundamental lambda(0) = 1079.5 nm. The complete determination of a d(ijk)(SHG) tensor in crystals of monoclinic or lower symmetry has not been published to our knowledge yet. Linear optical investigations indicate a wide range of wavelengths for phase matchable processes, The highest d(eff) we found along the phase matched direction of second harmonic generation at 1079.5 nm is 3.2 pm/V. This value is larger than that of many other substances, such as KTiOPO4 (KTP) or beta- BaB2O4 (BBO), being widely used in applications. (C) 1998 Elsevier Science Ltd. All rights reserved.
