5 SIMPLE TECHNIQUES FOR ER:YB:YAB CRYSTAL

The nonradiative changeover prices Adhere to the system WNR = W (0) exp(-alphap), in which p is the volume of phonons matching the Strength hole. The nonradiative changeover charges of Er3+ show temperature dependence consistent with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative peace rates is challenging by the
