5 ESSENTIAL ELEMENTS FOR ER:YB:YAB CRYSTAL

The nonradiative changeover rates Keep to the formulation WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the Electrical power gap. The nonradiative changeover fees of Er3+ exhibit temperature dependence according to the multiphonon rest idea. In Tm3+ the temperature dependence of nonradiative relaxation prices is intricate b
