THE DEFINITIVE GUIDE TO ER:YB:YAB CRYSTAL

The nonradiative transition costs Keep to the system WNR = W (0) exp(-alphap), in which p is the volume of phonons matching the Strength hole. The nonradiative changeover rates of Er3+ exhibit temperature dependence according to the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative rest premiums is complex through t
