THE BEST SIDE OF ER:YB:YAB CRYSTAL

The nonradiative changeover prices follow the method WNR = W (0) exp(-alphap), where by p is the number of phonons matching the Vitality gap. The nonradiative changeover prices of Er3+ exhibit temperature dependence consistent with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative peace prices is intricate because o
