A SECRET WEAPON FOR ER:YB:YAB CRYSTAL

The nonradiative changeover premiums Stick to the components WNR = W (0) exp(-alphap), wherever p is the number of phonons matching the Vitality hole. The nonradiative changeover charges of Er3+ show temperature dependence in step with the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative peace charges is complicated with
