Solid-State Laser Research Report: Energy Transfer in Non-Uniform Codoped Crystals

摘要

We develop an analytical model describing energy transfer between microscopically correlated donor-acceptor pairs in solid-state laser materials. We re-examine experimental data for several laser systems; host properties promoting enhanced non-radiative energy transfer are discussed. The results of this more general model are compared to the standard Foerster-Dexter approach of randomly placed donors and acceptors. This work is of interest to controlling thermal gradients, achieving new laser frequencies, and improving laser efficiency.
