THE BASIC PRINCIPLES OF ER:YB:YAB CRYSTAL

The nonradiative transition fees Stick to the formulation WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the Power hole. The nonradiative transition premiums of Er3+ show temperature dependence consistent with the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative relaxation costs is challengin
