A SECRET WEAPON FOR ER:YB:YAB CRYSTAL

The nonradiative changeover rates Stick to the formulation WNR = W (0) exp(-alphap), the place p is the quantity of phonons matching the Electricity gap. The nonradiative transition premiums of Er3+ exhibit temperature dependence per the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative rest premiums is difficult by the e
