- A method which takes into account normalized oscillator strengths is detailed for the calculation of parameters in Judd-Ofelt theory (B.R. Judd, Phys. Rev. 127, 750 (1962), G.S. Ofelt, J. Chem. Phys. 37, 511 (1962)). In the case of a Pr$\text{}^{3+}$ -doped fluorozirconate glass, the Judd-Ofelt parameters obtained in this way do not depend strongly on the transitions included in the fit. Particularly, it is no longer necessary to exclude the $\text{}^{3}$H$\text{}_{4}$ → $\text{}^{3}$P$\text{}_{2}$ transition from the analysis. Three modified theories (F. Auzel, S. Hubert, P. Delamoye, J. Lumin. 26, 251 (1982), A.A. Kornienko, A.A. Kaminskii, E.B. Dunina, Phys. Status Solidi B 157, 267 (1990)) are also considered but do not improve the calculated intensities when the energy of the 5d level is set to its experimentally determined value. Finally, in connection with 1.3 μ amplification, the 1.3 μ reabsorption ($\text{}^{1}$G$\text{}_{4}$ → $\text{}^{1}$D$\text{}_{2}$) oscillator strength is computed from the various models as well as the 1.3 μ emission branching ratio ($\text{}^{1}$G$\text{}_{4}$ → $\text{}^{3}$H$\text{}_{5}$/$\text{}^{1}$G$\text{}_{4}$ → $\text{}^{3}$H$\text{}_{6}$). The best agreement with experiment is obtained with the standard Judd-Ofelt theory.
