ER:YB:YAB CRYSTAL - AN OVERVIEW

The nonradiative changeover charges Adhere to the system WNR = W (0) exp(-alphap), wherever p is the amount of phonons matching the energy gap. The nonradiative transition rates of Er3+ exhibit temperature dependence consistent with the multiphonon rest concept. In Tm3+ the temperature dependence of nonradiative peace rates is challenging via the e
