Abstract
The pump efficiency of Pr-doped fluorozirconate amplifiers at 1300 nm is limited by nonradiative decay. A Pr3+1G4 excited state lifetime of 322 mus has been obtained in a mixed-halide glass. This is 2.9 times l onger than the lifetime in a fluorozirconate host. Numerical amplifier modeling combined with calculated emission cross sections predicts a comparable increase in amplifier pump efficiency. The mixed-halide 1G4 emission is peaked at 1310 nm.
