THE BASIC PRINCIPLES OF ER:YB:YAB CRYSTAL

The nonradiative transition rates follow the formulation WNR = W (0) exp(-alphap), wherever p is the amount of phonons matching the Strength hole. The nonradiative transition fees of Er3+ show temperature dependence in keeping with the multiphonon rest idea. In Tm3+ the temperature dependence of nonradiative relaxation charges is sophisticated from
