Abstract

The correlation between heat-treatment temperature for crystallization and orientation of surface crystalline phase, which should correspond to the intensity of second-order optical nonlinear susceptibility, in 30BaO-15 TiO2 -55 GeO2 (BTG55) crystallized glass was examined by measurements of x-ray diffraction (XRD) and second harmonic generation. A highly oriented fresnoite (Ba2 TiGe2 O8) or benitoite (BaTiGe3 O9) phase was found to nucleate from the same mother BTG55 glass depending on the heat-treatment temperature, and both the fresnoite and benitoite phases showed XRD patterns of surface crystallization. It was found that the crystallization behavior of the two phases was strongly affected by the heat-treatment temperature. Based on this finding, the nonlinear optical property has also been tailored using the heat-treatment procedures.
