Crystal and Glass Growth in BaO-B₂O₃-Al₂O₃ System by Floating Zone Pulling Down Method

Crystal and glass phase forming region in BaO-B₂O₃-Al₂O₃ system was investigated by floating zone pulling down method. The formed phase of the crystal and the glass were dependent on the composition and the growth procedures. The crystal and the glass were characterized from the viewpoint of the second harmonic generation (SHG). Weak SHG was observed at the composition of 5 mol% Al₂O₃ even on the glass. SHG profile as well as the β -BaB₂O₄ crystal was observed for the crystals grown from melt surrounding the BaB₂O₄ composition.

Keywords: BaB2O4, Al and Ga substitution, Pt tube and wire, Second harmonic generation
