ER:YB:YAB CRYSTAL - AN OVERVIEW

The nonradiative transition costs Stick to the components WNR = W (0) exp(-alphap), wherever p is the amount of phonons matching the energy hole. The nonradiative transition costs of Er3+ show temperature dependence in step with the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative leisure costs is complicated because of
