ER:YB:YAB CRYSTAL - AN OVERVIEW

The nonradiative changeover rates Stick to the components WNR = W (0) exp(-alphap), where by p is the number of phonons matching the Vitality gap. The nonradiative transition rates of Er3+ show temperature dependence in line with the multiphonon rest theory. In Tm3+ the temperature dependence of nonradiative rest premiums is difficult because of th
