ER:YB:YAB CRYSTAL - AN OVERVIEW

The nonradiative transition 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 in line with the multiphonon relaxation theory. In Tm3+ the temperature dependence of nonradiative peace fees is complex from the ex
