NOT KNOWN FACTUAL STATEMENTS ABOUT ER:YB:YAB CRYSTAL

The nonradiative transition rates Adhere to the components WNR = W (0) exp(-alphap), exactly where p is the quantity of phonons matching the Power hole. The nonradiative changeover rates of Er3+ show temperature dependence in keeping with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative peace rates is challenging v
