Li1.3Al0.3Ti1.7(PO4)3 conductive crystal lines composed of closely compacted fine particles were patterned on the surface of 13.9Li2O–8.9Al2O3–37.6TiO2–38.6P2O5–1NiO (mol %) precursor glass by a continuous wave Yb fiber laser irradiation (λ=1078 nm) using the nickel atom heat processing method. Homogeneous and smooth crystal lines with a uniform width of 30 μm were obtained with a laser power of 1.3 W. The Li+ ion conductivity of the laser patterned glass was about two orders of magnitude higher than that of the glass matrix due to the formation of Li1.3Al0.3Ti1.7(PO4)3 conductive crystalline phase by Yb fiber laser irradiation.
