Abstract

High-efficiency frequency up-conversion in trivalent erbium ion doped new fluoride glass matrix (ZnF2-AlF3-PbF2-LiF) was investigated. Under 950 nm laser-diode excitation, the glasses gave very intense green, weak red and violet emissions. The up-conversion mechanism is discussed. In addition, the infrared transmittance spectrum, the Raman spectrum and the lifetime of the trivalent erbium states in the samples were measured. The results illustrate the large potential of these new glasses for photonic applications.
