Abstract

The correlation between the orientation degree of surface crystalline phase and the second-order optical susceptibility, d coefficient for second-harmonic generation, in 30BaO-15TiO2-55GeO2 (BTG55) crystallized glass was investigated using x-ray diffraction measurements and a Maker fringe technique. The d coefficient in BTG55 crystallized glass was confirmed to depend on the orientation degree of the surface crystalline phase. An oriented fresnoite (Ba2TiGe2O8) phase was observed in transparent BTG55 crystallized glass which had been heat treated at 720 °C for 3 h. The orientation degree along the polar c axis in the fresnoite phase increased with increasing removal thickness by polishing from the surface up to several microns. A d coefficient in transparent BTG55 crystallized glass of 24±3 pm/V has been obtained, which is the largest value in crystallized glass ever reported.
