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

The nonradiative changeover premiums follow the components WNR = W (0) exp(-alphap), exactly where p is the number of phonons matching the Strength hole. The nonradiative transition rates of Er3+ show temperature dependence in step with the multiphonon relaxation principle. In Tm3+ the temperature dependence of nonradiative peace rates is sophistic
