ER:YB:YAB CRYSTAL - AN OVERVIEW

The nonradiative transition costs Keep to the formula WNR = W (0) exp(-alphap), the place p is the number of phonons matching the Strength hole. The nonradiative changeover costs of Er3+ show temperature dependence per the multiphonon relaxation principle. In Tm3+ the temperature dependence of nonradiative rest premiums is difficult from the existe
