- Abstract
The laser-induced crystallization method was applied to pattern β- BaB2 O4 crystals (β- BBO) in the inside of bulk glass plate and fibers of 8 Sm2 O3-42 BaO-50 B2 O3, in which the focal position of continuous wave ( CW) Yb: YVO4 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.
