ABSTRACT=<p>Bi<sub>2</sub>O<sub>3</sub>-based glasses are very attractive from the viewpoints of low-melting, high refractive index, and crystallization, and the research on their glasses and glass-ceramics is at the frontiers of glass science and technology. Non-linear optical Bi<sub>2</sub>ZnB<sub>2</sub>O<sub>7</sub> crystal lines with a high orientation were patterned in 3Sm<sub>2</sub>O<sub>3</sub>-30.3Bi<sub>2</sub>O<sub>3</sub>-33.3ZnO-33.3B<sub>2</sub>O<sub>3</sub> glass by using a laser-induced crystallization technique. It was confirmed from transmission electron microscope observations that crystals were formed in the inside of the glass, i.e., at the beneath of 4 μm from the surface, although lasers (Yb:YVO<sub>4</sub> laser with a wavelength of 1080 nm) were focused at the glass surface. A new potential for optical device applications was added in Bi<sub>2</sub>O<sub>3</sub>-based glasses from the present study.</p>
