Abstract: Ternary glasses of barium (Li-substituted) aluminum (Ga- or Si-substituted) borate were solidified by new technique using conventional Floating-zone Pulling Down system. It was difficult to grow single crystalline materials in this system. However, solidification of glasses was easy. Refractive indexes of these glasses were 1.5–1.7. Third-order nonlinear optical effects, χ (3), were larger than that of standard SiO2 glass at 355nm. Despite small refractive indexes as oxide glasses, large χ (3) were obtained.

Abstract: KNbO3 crystal is an incongruent melting crystal from a peritectic system. At first, a crystal was formed from the molten zone center of the stoichiometric composition using our original modified floating zone technique. Then the crystal was grown continuously using the firstly formed crystal as seed crystal. A small crystal with facets could be grown. The phase of the grown crystal was investigated in comparison to the phase grown by the conventional floating zone technique. [Copyright &y& Elsevier]
