Abstract

A high magnetic field of H = 10 T was applied to 30BaO-15TiO ₂-55GeO₂ glass through its crystallization process. It was found that the c-axis of Ba₂TiGe₂O₈ optical nonlinear/ferroelectric crystals oriented along the magnetic field. The second harmonic intensity of crystallized glass which the high magnetic field was applied perpendicular to the surface of glass was enhanced compared with a conventional crystallization in no magnetic field. Transparencies, photorefractive indices and thicknesses were also measured. As a result, crystal orientation of Ba₂TiGe₂O₈ in glass matrix induced by a high magnetic field causes improvement of transparency and low value of photorefractive index.
