The laser-induced crystallization method was applied to pattern -BaB2O4 crystals (-BBO) in the inside of bulk glass plate and fibers of 8Sm2O342BaO50B2O3, in which the focal position of continuous wave (CW) Yb:YVO4 fiber lasers (power: 0.91.0W, scanning speed: 2m/s) with a wavelength of 1080nm was moved gradually from the surface to the inside. It was confirmed from micro-Raman scattering spectra, second harmonic generation, and transmission electron microscope observations that -BBO crystals are patterned in the inside of glass plate and fibers (diameter: 110m) and are highly oriented that is c-axis orientation, along the laser scanning direction. This study proposes the direct and simple processing for the fabrication of glass fibers consisting of optical functional crystal cores.
