ER:YB:YAB CRYSTAL - AN OVERVIEW

The nonradiative changeover fees follow the components WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the Electrical power gap. The nonradiative changeover charges of Er3+ show temperature dependence in step with the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative rest rates is difficult with the
