THE DEFINITIVE GUIDE TO ER:YB:YAB CRYSTAL

The nonradiative changeover prices follow the formulation WNR = W (0) exp(-alphap), wherever p is the amount of phonons matching the energy gap. The nonradiative changeover rates of Er3+ exhibit temperature dependence in line with the multiphonon rest concept. In Tm3+ the temperature dependence of nonradiative relaxation charges is complicated with
