THE 5-SECOND TRICK FOR ER:YB:YAB CRYSTAL

The nonradiative transition rates follow the formulation WNR = W (0) exp(-alphap), where by p is the volume of phonons matching the Power gap. The nonradiative changeover premiums of Er3+ exhibit temperature dependence per the multiphonon peace principle. In Tm3+ the temperature dependence of nonradiative leisure fees is complicated from the existe
