Laser Patterning of Non-Linear Optical Bi2ZnB2O7 Crystal Lines in Glass
نویسندگان
چکیده
Bi2O3-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 Bi2ZnB2O7 crystal lines with a high orientation were patterned in 3Sm2O3-30.3Bi2O3-33.3ZnO-33.3B2O3 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 4μm from the surface, although lasers (Yb:YVO4 laser with a wavelength of 1080 nm) were focused at the glass surface. A new potential for optical device applications was added in Bi2O3-based glasses from the present study.
