This Letter reports intense emission at and broadband emission at from -doped fluorophosphate glass. The fluorescence characteristics and energy transfer upon excitation of a conventional laser diode are investigated. Based on the fluorescence spectra and lifetime measurement, the effect of and ions on intense emission in fluorophosphate glass is demonstrated. It is also found that the effective bandwidth of emission due to and ions can reach as high as . These results indicate that the advantageous spectroscopic characteristics of triply doped fluorophosphate glass together with the outstanding thermal properties may become an attractive host for the mid-IR solid state lasers.
