THE BEST SIDE OF ER:YB:YAB CRYSTAL

The nonradiative transition premiums follow the method WNR = W (0) exp(-alphap), in which p is the amount of phonons matching the Power gap. The nonradiative changeover premiums of Er3+ exhibit temperature dependence consistent with the multiphonon rest theory. In Tm3+ the temperature dependence of nonradiative relaxation prices is complicated thro
