THE 5-SECOND TRICK FOR ER:YB:YAB CRYSTAL

The nonradiative changeover premiums Keep to the formulation WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the energy gap. The nonradiative changeover costs of Er3+ show temperature dependence per the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative leisure rates is intricate by the existenc
