BiB3O6(BIBO)晶体的透射光谱与KTP进行了比较。通过在 (010) 平面上以不同相位匹配 (PM) 方向切割 BIBO 样品，我们在这种低对称晶体中获得了高效的脉冲激光辐射二次谐波产生 (SHG)。对于BIBO晶体，（168.9°，90°）方向比（11.1°，90°）方向表现出更大的有效非线性光学（NLO）系数。对于2.4毫米长（168.9°，90°）切割的BIBO，倍频转换效率可以达到67.7%，而在相同条件下，4.7毫米长（11.1°，90°）切割的BIBO的效率为58%左右。
The transmission spectra of BiB3O6(BIBO) crystals are compared with KTP. With BIBO samples cut in different phase matching (PM) directions in (010) plane, we obtain efficient second harmonic generation (SHG) of pulsed laser radiation in this low symmetric crystal. For BIBO crystal, the direction (168.9°, 90°) exhibits a larger efficient nonlinear optical (NLO) coefficient than the direction (11.1°, 90°). For a 2.4 mm long, (168.9°, 90°)-cut BIBO, the SHG conversion efficiency can reach 67.7%, while at the same conditions the efficiency of a 4.7 mm long, (11.1°, 90°)-cut BIBO is 58% or so.
