ER:YB:YAB CRYSTAL - AN OVERVIEW

The nonradiative transition fees Keep to the formulation WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the Vitality gap. The nonradiative changeover charges of Er3+ show temperature dependence in step with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative rest premiums is difficult via the exis
