THE ULTIMATE GUIDE TO ER:YB:YAB CRYSTAL

The nonradiative changeover rates Keep to the formulation WNR = W (0) exp(-alphap), wherever p is the volume of phonons matching the energy hole. The nonradiative changeover rates of Er3+ exhibit temperature dependence per the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative rest costs is challenging via the existence of
