ER:YB:YAB CRYSTAL FOR DUMMIES

The nonradiative changeover prices follow the components WNR = W (0) exp(-alphap), where by p is the quantity of phonons matching the Vitality hole. The nonradiative changeover rates of Er3+ exhibit temperature dependence according to the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative rest premiums is complex thr
