ER:YB:YAB CRYSTAL - AN OVERVIEW

The nonradiative changeover fees Adhere to the method WNR = W (0) exp(-alphap), exactly where p is the volume of phonons matching the Strength hole. The nonradiative transition fees of Er3+ exhibit temperature dependence in step with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative peace rates is difficult because
