Intensity parameters and laser analysis of Pr3+ and Dy3+ in oxide glasses

Abstract

Intensity parameters (ΩΛ) of Pr3+ and Dy3+ have been obtained in tellurite, borate and phosphate glasses. It has been found that ΩΛ calculated by exlusion of hypersensitive transitions, gives a better fit between measured and calculated lifetimes and branching ratios than those including hypersensitive transitions. Using these parameters and calculated matrix elements U(Λ), radiative transition probabilities, branching ratios and integrated cross sections for stimulated emission were calculated for 3P0, 3P1 and 1D2 excited states of Pr3+ and 4F 9 2 excited state of Dy3+. Potential transitions are indicated. © 1979.
