Fluorescence in erbium doped gallium lanthanum sulphide: potential for mid-IR waveguide laser

摘要

Fluorescence is reported in waveguides fabricated via the ultrafast laser inscription technique in Erbium doped Gallium Lanthanum Sulphide (Er3+:GLS) for mid-infrared laser applications. The pump wavelength was 980nm leading to mid-infrared transition at 2.75 µm.
