A SECRET WEAPON FOR ER:YB:YAB CRYSTAL

The nonradiative transition premiums Stick to the components WNR = W (0) exp(-alphap), the place p is the number of phonons matching the Electricity hole. The nonradiative transition costs of Er3+ show temperature dependence per the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative rest costs is complicated with the exist
