5 SIMPLE TECHNIQUES FOR ER:YB:YAB CRYSTAL

The nonradiative changeover rates Keep to the formula WNR = W (0) exp(-alphap), the place p is the number of phonons matching the Vitality gap. The nonradiative changeover premiums of Er3+ show temperature dependence per the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative rest prices is difficult because of the existenc
