Compositional dependence of optical properties of Nd3+ in gallate glasses

Compositional dependence of optical properties of Nd3+ in gallate glasses
The Judd-Ofelt parameters, spontaneous emission probabilities from the 4F3/2 level, quantum efficiency, and stimulated emission cross section of the 4F3/2 to 4I11/2 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 pm2 because of their high refractive indexes. The variations of the JO parameters with composition are discussed in terms of glass structure.

Abstract

The Judd-Ofelt parameters, spontaneous emission probabilities from the 4F3/2 level, quantum efficiency, and stimulated emission cross section of the 4F3/2 to 4I11/2 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 pm2 because of their high refractive indexes. The variations of the JO parameters with composition are discussed in terms of glass structure.
