ER:YB:YAB CRYSTAL OPTIONS

The nonradiative transition costs Keep to the formulation WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the energy gap. The nonradiative changeover rates of Er3+ exhibit temperature dependence in line with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative relaxation costs is complex with the e
