ER:YB:YAB CRYSTAL - AN OVERVIEW

The nonradiative transition costs follow the system WNR = W (0) exp(-alphap), the place p is the volume of phonons matching the Strength hole. The nonradiative transition charges of Er3+ show temperature dependence consistent with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative peace premiums is complex through th
