Abstract

Oxyfluoride glasses with a small amount of NiO are prepared using a melt quenching technique. The spatially selected crystallization of CaF2 crystals is induced on the glass surface by irradiations of laser with a wavelength of λ=1080nm. Lines including CaF2 crystals are patterned by laser irradiations with a power of P=1.7W and a scan speed of S=2μm/s, and crystallization of CaF2 crystals were confirmed from X-ray diffraction (XRD) analysis. Dots and lines consisting of CaF2 crystals on an ErF3-doped oxyfluoride glass are also patterned by laser irradiations with some laser irradiation conditions, and Er3+ ions into CaF2 crystals is confirmed by micro-photo luminescence spectrum measurements.
