The laser‐induced crystallization method was applied to pattern β‐ BaB 2 O 4 crystals (β‐ BBO ) in the inside of bulk glass plate and fibers of 8 Sm 2 O 3 –42 BaO –50 B 2 O 3 , in which the focal position of continuous wave ( CW ) Yb : YVO 4 fiber lasers (power: 0.9–1.0 W, scanning speed: 2 μm/s) with a wavelength of 1080 nm 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 β‐ BBO crystals are patterned in the inside of glass plate and fibers (diameter: 110 μm) 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.
