A study of the optical properties of Nd3+ ion in TeO2–PbF2–AlF3 glasses has been carried out for different
Nd3+ concentrations. Based on the Judd–Ofelt theory, intensity parameters and radiative properties were
determined from the absorption spectra. Focusing on the suitability of this host for laser applications, the
spectroscopic quality factor v was obtained with a value of 1.07, a value of the order of other
compositions proposed as laser hosts. For the most intense emission corresponding with the
4F3/2?4I11/2 transition (1.06 lm), the absorption and emission and have been calculated with values
of 1.20 10 20 cm2, 2.08 10 20 cm2. A positive value for the gain cross-sections has been found for a
population inversion factor c of 0.4 in the spectral range from 1060 to 1110 nm. All these results suggest
the potentially use of this system as a laser host.
