5 SIMPLE TECHNIQUES FOR ER:YB:YAB CRYSTAL

The nonradiative transition costs Stick to the components WNR = W (0) exp(-alphap), the place p is the number of phonons matching the Strength hole. The nonradiative transition costs of Er3+ show temperature dependence consistent with the multiphonon peace principle. In Tm3+ the temperature dependence of nonradiative rest charges is sophisticated v
