ER:YB:YAB CRYSTAL - AN OVERVIEW

The nonradiative transition fees Keep to the method WNR = W (0) exp(-alphap), in which p is the amount of phonons matching the Vitality hole. The nonradiative changeover prices of Er3+ exhibit temperature dependence consistent with the multiphonon rest concept. In Tm3+ the temperature dependence of nonradiative leisure fees is difficult because of
