采用激光诱导晶化法，将波长为1080 nm的Yb：YVO 4光纤激光器（功率0.9-1.0 W，扫描速度2 μm/s）的焦点位置由表面向内部逐渐移动，在块体玻璃板和8 Sm 2 O3 - 42 BaO-50 B2 O3纤维内部图案化β-BaB 2 O 4晶体（β-BBO）。通过显微拉曼散射光谱、二次谐波发生、透射电子显微镜观察，确认了β-BBO晶体在玻璃板和纤维（直径110 μm）的内部图案化，并且沿着激光扫描方向沿着c轴取向的高度取向。本研究提出一种直接且简单的制程，以制作具有光学功能性晶芯的玻璃光纤。
The laser‐induced crystallization method was applied to pattern β‐BaB2O4crystals (β‐BBO) in the inside of bulk glass plate and fibers of 8Sm2O3–42BaO–50B2O3, in which the focal position of continuous wave (CW) Yb:YVO4fiber 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 isc‐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.
