ER:YB:YAB CRYSTAL OPTIONS

The nonradiative transition charges Keep to the formulation WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the Vitality hole. The nonradiative transition costs of Er3+ show temperature dependence per the multiphonon relaxation idea. In Tm3+ the temperature dependence of nonradiative peace charges is challenging from the exist
