ER:YB:YAB CRYSTAL - AN OVERVIEW

The nonradiative changeover charges Keep to the formulation WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the Vitality hole. The nonradiative changeover charges of Er3+ show temperature dependence per the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative rest costs is complex because of the existen
