Paper Abstract

Energy transfer dynamics in fluorozirconate glass doubly-doped with Yb3+:Er3+ and Ce3+:Er3+ have been analyzed by using rate equation formalism. For the Yb3+:Er3+-ZBLAN glass, the macroscopic energy transfer parameters, cross-relaxation coefficients, were derived to be 1.1*10-17s-1cm3 and 2.0*10-17s-1cm3 for the forward energy transfer (Yb3+ → Er3+) and the backward transfer (Er3+ → Yb3+), respectively. After experimentally investigating fluorescence characteristics of Er3+ ions in the Ce3+:Er3+-ZBLAN glass, taking into account of up-conversion and energy transfer effect, a resonant cascade energy transfer model was developed, with which the operating mechanism of the Ce3+:Er3+-ZBLAN fiber laser was explained theoretically. The potentiality of the rare-earth-codoped fluoride glass as one of the most promising laser materials is demonstrated.
