5 SIMPLE TECHNIQUES FOR ER:YB:YAB CRYSTAL

The nonradiative changeover rates Keep to the formulation WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the Electricity gap. The nonradiative changeover fees of Er3+ exhibit temperature dependence in step with the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative relaxation costs is difficult becau
