A SECRET WEAPON FOR ER:YB:YAB CRYSTAL

The nonradiative changeover rates Adhere to the method WNR = W (0) exp(-alphap), exactly where p is the volume of phonons matching the Vitality gap. The nonradiative transition rates of Er3+ exhibit temperature dependence consistent with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative peace premiums is difficult v
