ER:YB:YAB CRYSTAL - AN OVERVIEW

The nonradiative changeover costs Stick to the components WNR = W (0) exp(-alphap), the place p is the amount of phonons matching the Electricity gap. The nonradiative changeover rates of Er3+ show temperature dependence consistent with the multiphonon rest idea. In Tm3+ the temperature dependence of nonradiative leisure costs is challenging throug
