Abstract

A measurement technique is described in which the radiative quantum efficiency of certain transitions in rare-earth–doped glasses can be determined based only on relative fluorescence measurements. We calibrate the emission from the level of interest by measuring emission into that level from a higher excited level. Application of the technique to Pr3+-doped sulfide glasses yields quantum efficiencies for the 1G43H5 transition as high as 60%, in good agreement with measurements using the integrating sphere technique. Calculated efficiency values based on the Judd–Ofelt technique are shown to be subject to inherent uncertainties.
