ER:YB:YAB CRYSTAL - AN OVERVIEW

The nonradiative transition costs Keep to the formulation WNR = W (0) exp(-alphap), where by p is the number of phonons matching the Power gap. The nonradiative changeover fees of Er3+ show temperature dependence per the multiphonon rest theory. In Tm3+ the temperature dependence of nonradiative peace premiums is sophisticated because of the existe
