Optical absorption and emission spectra and fluorescence lifetimes were measured for Nd<sup>3+</sup> in a series of five oxide glasses. Spectroscopic parameters such as the stimulated-emission cross section, the effective bandwidth of the <sup>4</sup>F<sub>3/2</sub>→<sup>4</sup>I<sub>11/2</sub> transition, and the radiative lifetime of the <sup>4</sup>F<sub>3/2</sub> level were obtained, and their dependence on the composition of the glass is described. In addition, the relative gain properties for the <sup>4</sup>F<sub>3/2</sub>→ <sup>4</sup>I<sub>11/2</sub> transition in various glasses are evaluated by the classic gain equation model.
