THE ULTIMATE GUIDE TO ER:YB:YAB CRYSTAL

The nonradiative transition rates Keep to the formulation WNR = W (0) exp(-alphap), wherever p is the volume of phonons matching the Power gap. The nonradiative transition prices of Er3+ exhibit temperature dependence per the multiphonon rest concept. In Tm3+ the temperature dependence of nonradiative rest rates is complicated because of the existe
