Studies of the Sensitization Mechanisms of Rare Earth Detection and Laser Materials.
Abstract
The report summarizes spectroscopic studies of energy transfer in rare earths with particular attention devoted to transfer phenomena in multiply sensitized (Er-TM)Ho(3+):YLF (LiYF4). Energy transfer was studied as a function of Ho(3+) and Tm(3+) concentration and temperature. A model for the Tm-Ho transfer versus Ho and Tm concentration is presented which predicts the observed dependence of the Ho lifetime and fluorescence yield on the Tm:Ho population ratios and the temperature. The effects of the transfer phenomena on the 2 micrometer lasing efficiency of multiply sensitized Ho:YLF (alpha beta LF) are discussed.
