A SECRET WEAPON FOR ER:YB:YAB CRYSTAL

The nonradiative changeover rates Stick to the formula WNR = W (0) exp(-alphap), where by p is the quantity of phonons matching the Vitality hole. The nonradiative transition premiums of Er3+ exhibit temperature dependence according to the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative rest costs is complicated from th
