N2 - Laser properties of fluoride and oxide glasses containing neodymium (III), and holmium(III) depend on the pumping efficiency, lifetimes of the excited and terminal levels and stimulated peak cross-sections. We have determined these properties in oxide glass (tellurite) having a composition of 35ZnO:65TeO2 and fluoride glass (ZBLA) having composition 57ZrF4:34BaF2:5LaF3:4AlF3, or (PBLA) having a composition 36PbF2: 24ZnF2:35GaF3:3YF3:2AlF3 for neodymium(III) and holmium(III). It was shown that multiphonon relaxation (in the case of energy difference less than 3000 cm-1) is always orders of magnitude lower in the fluoride glass than in the tellurite glass, which was chosen as a model for oxide glass. No significant difference was found for concentration quenching between the two kinds of glasses.
