5 SIMPLE TECHNIQUES FOR ER:YB:YAB CRYSTAL

The nonradiative changeover fees Adhere to the components WNR = W (0) exp(-alphap), where by p is the quantity of phonons matching the Strength gap. The nonradiative transition fees of Er3+ show temperature dependence per the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative rest rates is complex through the existence of
