A SIMPLE KEY FOR ER:YB:YAB CRYSTAL UNVEILED

The nonradiative transition fees Stick to the formulation WNR = W (0) exp(-alphap), where p is the volume of phonons matching the Electrical power hole. The nonradiative changeover rates of Er3+ show temperature dependence consistent with the multiphonon relaxation idea. In Tm3+ the temperature dependence of nonradiative rest costs is complex with
