ER:YB:YAB CRYSTAL - AN OVERVIEW

The nonradiative transition fees Stick to the formulation WNR = W (0) exp(-alphap), in which p is the number of phonons matching the energy hole. The nonradiative changeover fees of Er3+ show temperature dependence in keeping with the multiphonon rest idea. In Tm3+ the temperature dependence of nonradiative leisure rates is intricate via the existe
