Abstract

We estimated an optical second order nonlinearity of ferroelastic Ba2TiGe2O8 crystal in transparent crystallized glasses by means of Maker fringe technique for the first time. Transparent crystallized glasses were fabricated using a glass with the composition of 30BaO.15TiO2.55GeO2, similar to that of Ba2TiGe2O8. The crystalline layer consisting of highly oriented Ba2TiGe2O8 crystals was formed at the surface of about 9 µm thickness, and a clear second harmonic generation was observed. The optical second order nonlinearity of d33 for transparent Ba2TiGe2O8 crystallized glass was found to be ~10 pm/V, being comparable to d22 and d31 of LiNbO3, and demonstrating that Ba2TiGe2O8 crystal is an excellent candidate for nonlinear optical crystals.
