THE GREATEST GUIDE TO ER:YB:YAB CRYSTAL

The nonradiative changeover fees Keep to the system WNR = W (0) exp(-alphap), where by p is the volume of phonons matching the Power gap. The nonradiative transition rates of Er3+ show temperature dependence in keeping with the multiphonon peace concept. In Tm3+ the temperature dependence of nonradiative leisure prices is challenging because of the
