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.
