CONSIDERATIONS TO KNOW ABOUT ER:YB:YAB CRYSTAL

The nonradiative changeover rates Adhere to the formulation WNR = W (0) exp(-alphap), where p is the volume of phonons matching the Strength hole. The nonradiative changeover prices of Er3+ show temperature dependence per the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative rest premiums is difficult via the existence of
