The Judd-Ofelt parameters, spontaneous emission probabilities from the 4F(3/2) level, quantum efficiency, and stimulated emission cross section of the 4F(3/2) to 4I(11/2) transition for Nd3+ are studied for potassium tantalum and lead bismuth gallate glasses. The results reveal that the tantalum gallate glasses have high Omega2 values being comparable to that of Ge-Ga-S glass. The lead bismuth gallate glasses have high stimulated emission cross sections over 4 pm^2 because of their high refractive indexes. The variations of the JO parameters with composition are discussed in terms of glass structure.
