ER:YB:YAB CRYSTAL - AN OVERVIEW

The nonradiative changeover prices Adhere to the formulation WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the energy gap. The nonradiative changeover rates of Er3+ exhibit temperature dependence consistent with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative peace prices is sophisticated f
