ER:YB:YAB CRYSTAL - AN OVERVIEW

The nonradiative changeover charges Keep to the method WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the energy gap. The nonradiative transition costs of Er3+ show temperature dependence in step with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative relaxation prices is sophisticated via the
