THE DEFINITIVE GUIDE TO ER:YB:YAB CRYSTAL

The nonradiative changeover fees follow the formulation WNR = W (0) exp(-alphap), in which p is the number of phonons matching the Power gap. The nonradiative changeover prices of Er3+ exhibit temperature dependence in line with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative rest premiums is sophisticated because
