Lasing performance of Nd3+-fluoroaluminate glasses has been predicted with the help of laser parameters for the transitions 4F3/2 → 4I9/2, 4F3/2 → 4I11/2 and 4F3/2 → 4I13/2 in the near infrared region. Judd-Ofelt parameters have been used for the calculations of different laser parameters. Analysis yielded some of the important spectroscopic parameters, namely radiative transition probabilities, radiative lifetimes and fluorescence branching ratios. The branching ratios for 4F3/2 → 4I13/2 and their emission to Exited State Absorption (ESA) intensity ratios are higher at the glasses containing Pb2+ ion while their radiative lifetime shows the opposite trend. The overall results reported here showed that Nd3+doped fluoroaluminate glasses containing Pb2+ is a promising active laser material with high refraction index.
