ER:YB:YAB CRYSTAL OPTIONS

The nonradiative changeover premiums follow the components WNR = W (0) exp(-alphap), in which p is the volume of phonons matching the Strength gap. The nonradiative changeover rates of Er3+ show temperature dependence according to the multiphonon leisure concept. In Tm3+ the temperature dependence of nonradiative leisure charges is complicated beca
