WHAT DOES ER:YB:YAB CRYSTAL MEAN?

The nonradiative changeover fees Keep to the formulation WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the energy gap. The nonradiative transition costs of Er3+ exhibit temperature dependence per the multiphonon peace idea. In Tm3+ the temperature dependence of nonradiative relaxation prices is difficult from the existence
