A SECRET WEAPON FOR ER:YB:YAB CRYSTAL

The nonradiative changeover premiums Keep to the formulation WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the Vitality hole. The nonradiative transition rates of Er3+ exhibit temperature dependence according to the multiphonon rest concept. In Tm3+ the temperature dependence of nonradiative leisure fees is complicated thro
