ER:YB:YAB CRYSTAL - AN OVERVIEW

The nonradiative transition premiums follow the method WNR = W (0) exp(-alphap), in which p is the quantity of phonons matching the Strength gap. The nonradiative changeover costs of Er3+ show temperature dependence in line with the multiphonon rest concept. In Tm3+ the temperature dependence of nonradiative peace costs is intricate with the existe
