THE GREATEST GUIDE TO ER:YB:YAB CRYSTAL

The nonradiative changeover fees follow the components WNR = W (0) exp(-alphap), wherever p is the volume of phonons matching the energy hole. The nonradiative changeover premiums of Er3+ show temperature dependence in keeping with the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative relaxation charges is intricate
