THE 2-MINUTE RULE FOR ER:YB:YAB CRYSTAL

The nonradiative transition costs follow the system WNR = W (0) exp(-alphap), exactly where p is the volume of phonons matching the Vitality hole. The nonradiative changeover charges of Er3+ exhibit temperature dependence according to the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative peace costs is complicated with
