5 SIMPLE TECHNIQUES FOR ER:YB:YAB CRYSTAL

The nonradiative changeover costs follow the system WNR = W (0) exp(-alphap), in which p is the volume of phonons matching the Vitality hole. The nonradiative changeover prices of Er3+ show temperature dependence in step with the multiphonon leisure principle. In Tm3+ the temperature dependence of nonradiative peace rates is challenging via the exi
