THE BEST SIDE OF ER:YB:YAB CRYSTAL

The nonradiative changeover rates Adhere to the formulation WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the Power gap. The nonradiative changeover prices of Er3+ show temperature dependence consistent with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative relaxation charges is complicated thr
