BiB3O6 (BIBO) single crystals with sizes of 44mm × 24 mm × 10 mm and weight of 24.7 g have been successfully grown by the top-seeded method. In this note, the preparation of seed, the growth of crystal and some problems encountered are reported. The lattice parameters of B1BO are a =7.1203(7)A, b = 4.9948(7)A, c = 6.5077(7)A, β =105.586(8) ", V=222.93(5)A3, which were determined by BRUKER-P4 four-circle diffractometer. BIBO is biaxial crystal and the relative orientation of (X, Y, Z) with regard to (a, b, c) is: X∥b, (Y, c) =47.2 °, (Z, a) = 31.6°, determined by the X-ray analysis combined with polarized microscopy. The second-harmonic-generation (SHG) conversion efficiency of the sample for 1.064 μm light is up to 67.7%. We have also obtained the third harmonic generation (THG) of 1.064 μm,namely, 1.064 μm + 0.532 tm →0.355 μm. BIBO crystal is free of moisture and hygroscopy.
