THE ULTIMATE GUIDE TO ER:YB:YAB CRYSTAL

The nonradiative changeover rates Stick to the formulation WNR = W (0) exp(-alphap), where by p is the quantity of phonons matching the Strength gap. The nonradiative transition charges of Er3+ exhibit temperature dependence consistent with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative rest costs is intricate fr
