5 ESSENTIAL ELEMENTS FOR ER:YB:YAB CRYSTAL

The nonradiative transition premiums Keep to the formulation WNR = W (0) exp(-alphap), where by p is the quantity of phonons matching the energy gap. The nonradiative changeover rates of Er3+ exhibit temperature dependence consistent with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative leisure fees is difficult be
