An analysis of the Judd-Ofelt phenomenological intensity parameters for Pr3+ ions in phosphate and silica glasses is made. The experimental oscillator strengths of the different transitions are determined from the absorption spectra. A consistent set of parameters is obtained only with the inclusion of odd rank third order intensity parameters in the calculation. With the modified parameters, the quality of the fit to the oscillator strengths is better than those obtained with the standard Judd-Ofelt model.
