THE 2-MINUTE RULE FOR ER:YB:YAB CRYSTAL

The nonradiative transition costs Keep to the method WNR = W (0) exp(-alphap), where by p is the quantity of phonons matching the energy hole. The nonradiative changeover fees of Er3+ exhibit temperature dependence per the multiphonon leisure principle. In Tm3+ the temperature dependence of nonradiative leisure fees is complex via the existence of
