5 SIMPLE TECHNIQUES FOR ER:YB:YAB CRYSTAL

The nonradiative transition charges follow the formulation WNR = W (0) exp(-alphap), the place p is the quantity of phonons matching the Vitality gap. The nonradiative transition fees of Er3+ exhibit temperature dependence according to the multiphonon leisure principle. In Tm3+ the temperature dependence of nonradiative relaxation charges is compli
