THE DEFINITIVE GUIDE TO ER:YB:YAB CRYSTAL

The nonradiative changeover rates follow the method WNR = W (0) exp(-alphap), wherever p is the number of phonons matching the energy gap. The nonradiative changeover rates of Er3+ show temperature dependence in line with the multiphonon relaxation idea. In Tm3+ the temperature dependence of nonradiative leisure premiums is complex through the exis
