THE 2-MINUTE RULE FOR ER:YB:YAB CRYSTAL

The nonradiative transition costs Stick to the formulation WNR = W (0) exp(-alphap), the place p is the quantity of phonons matching the Electrical power hole. The nonradiative transition rates of Er3+ show temperature dependence in line with the multiphonon rest idea. In Tm3+ the temperature dependence of nonradiative rest fees is complex by the e
