ER:YB:YAB CRYSTAL OPTIONS

The nonradiative transition rates Keep to the formulation WNR = W (0) exp(-alphap), where p is the amount of phonons matching the Electrical power hole. The nonradiative changeover charges of Er3+ show temperature dependence per the multiphonon peace concept. In Tm3+ the temperature dependence of nonradiative leisure rates is intricate by the exist
