THE ULTIMATE GUIDE TO ER:YB:YAB CRYSTAL

The nonradiative transition rates Adhere to the method WNR = W (0) exp(-alphap), in which p is the volume of phonons matching the Strength hole. The nonradiative transition charges of Er3+ show temperature dependence consistent with the multiphonon leisure principle. In Tm3+ the temperature dependence of nonradiative rest fees is difficult with the
