ER:YB:YAB CRYSTAL - AN OVERVIEW

The nonradiative changeover prices follow the components WNR = W (0) exp(-alphap), the place p is the number of phonons matching the Electrical power gap. The nonradiative changeover rates of Er3+ exhibit temperature dependence consistent with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative relaxation prices is ch
