Optical absorption and emission spectra and fluorescence lifetimes were measured for Nd3+ in a series of five oxide glasses. Spectroscopic parameters such as the stimulated-emission cross section, the effective bandwidth of the 4F3/2→4I11/2 transition, and the radiative lifetime of the 4F3/2 level were obtained, and their dependence on the composition of the glass is described. In addition, the relative gain properties for the 4F3/2→ 4I11/2 transition in various glasses are evaluated by the classic gain equation model.
