5 ESSENTIAL ELEMENTS FOR ER:YB:YAB CRYSTAL

The nonradiative transition charges Keep to the formulation WNR = W (0) exp(-alphap), exactly where p is the quantity of phonons matching the Power hole. The nonradiative changeover rates of Er3+ exhibit temperature dependence according to the multiphonon rest concept. In Tm3+ the temperature dependence of nonradiative peace prices is intricate by
