5 SIMPLE TECHNIQUES FOR ER:YB:YAB CRYSTAL

The nonradiative changeover premiums follow the system WNR = W (0) exp(-alphap), where p is the volume of phonons matching the energy gap. The nonradiative changeover rates of Er3+ show temperature dependence in keeping with the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative leisure prices is difficult because of the e
