We examined the laser-induced crystallization to form the fresnoite type Ba2TiGe2O8 crystal line patterns in transition metal ion doped BaO-TiO2-GeO2 glass. Ba2TiGe2O8 crystal line was written in 0.6FeO-33.3BaO-16.7TiO2-50GeO2 glass by continuous wave yttrium-aluminum-garnet (YAG) laser irradiation. We obtained polarization dependence of Raman spectra in crystal line pattern. Second harmonic generation (SHG) indicated unique fringe patterns from Ba2TiGe2O8 crystal lines.
