A SECRET WEAPON FOR ER:YB:YAB CRYSTAL

The nonradiative changeover rates Stick to the components WNR = W (0) exp(-alphap), wherever p is the number of phonons matching the Electricity gap. The nonradiative transition costs of Er3+ show temperature dependence per the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative rest prices is intricate by the existence of
