THE BEST SIDE OF ER:YB:YAB CRYSTAL

The nonradiative transition charges follow the system WNR = W (0) exp(-alphap), in which p is the volume of phonons matching the Vitality hole. The nonradiative changeover charges of Er3+ show temperature dependence in line with the multiphonon leisure concept. In Tm3+ the temperature dependence of nonradiative leisure premiums is sophisticated by
