ER:YB:YAB CRYSTAL - AN OVERVIEW

The nonradiative changeover costs Keep to the method WNR = W (0) exp(-alphap), wherever p is the number of phonons matching the Vitality hole. The nonradiative changeover charges of Er3+ exhibit temperature dependence in line with the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative rest costs is sophisticated by t
