THE BEST SIDE OF ER:YB:YAB CRYSTAL

The nonradiative changeover fees Stick to the formulation WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the energy gap. The nonradiative changeover prices of Er3+ exhibit temperature dependence consistent with the multiphonon peace concept. In Tm3+ the temperature dependence of nonradiative rest premiums is complex with the
