利用顶部籽晶法生长了尺寸为 ４４ mm × ２４ ｍｍ × １０ ｍｍ，重 ２４．７ ｇ的 Ｂi Ｂ３Ｏ６单晶．对籽晶制备、单晶生长以及遇到的问题进行了详细的报道．利用四圆衍射仪测定了晶体结构：ａ＝７．１２０３（７）Ａ，ｂ＝４．９９４８（７）Ａ， ｃ＝ ６．５０７７（７）Ａ， β＝ １０５．５８６（８）°， Ｖ＝ ２２２．９３（５）Ａ３．利用分光光度计测试了 １９０～３２００ nm的透光波段，透过率为８０％左右．Ｂi Ｂ３Ｏ６是双轴晶体，利用偏光显微镜和Ｘ射线衍射仪，进行了晶体折射率主轴的定向工作，结果是： ｂ∥Ｘ，（ａ， Ｚ）= ３１．６°，（ｃ， Ｙ）＝ ４７．２°．利用 ｌ．０６μｍ光源获得了高达 ６７．７％的倍频转换效率，也得到了（１．０６＋０．５３２）μm→ ０ ．３５５μｍ的三倍频效应．ＢiＢ３Ｏ６晶体不潮解．
Bi B3O6 single crystal with a size of 44 mm × 24 mm × 10 mm and a weight of 24.7 g was grown by top-seed method. Seed preparation, single crystal growth and the problems encountered were reported in detail. The crystal structure was determined by four-circle diffractometer: a = 7.1203 (7) A, b = 4.9948 (7) A, c = 6.5077 (7) A, V = 222.93 (5) A3. The transmission band of 190 ~ 3200 nm was measured by spectrophotometer and the transmittance was about 80%. Bi B3O6 is a biaxial crystal. The orientation operation of the crystal refractive index main axis was performed using a polarization microscope and an X-ray diffractometer. As a result, b∥X, (a, Z) = 31.6 °, (c, Y) = 47.2 °. Use l. The frequency conversion efficiencies of up to 67.7% were obtained for the 06 μm light source and also obtained (1.06 + 0.532) μm → 0. 355μm triple frequency effect. BiB3O6 crystals do not deliquesce.
