THE DEFINITIVE GUIDE TO ER:YB:YAB CRYSTAL

The nonradiative transition fees Stick to the components WNR = W (0) exp(-alphap), the place p is the number of phonons matching the Power gap. The nonradiative transition rates of Er3+ show temperature dependence consistent with the multiphonon leisure concept. In Tm3+ the temperature dependence of nonradiative leisure costs is intricate via the e
