A SECRET WEAPON FOR ER:YB:YAB CRYSTAL

The nonradiative transition fees Stick to the components WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the energy hole. The nonradiative changeover charges of Er3+ show temperature dependence in step with the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative rest premiums is difficult because of t
