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

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