THE BEST SIDE OF ER:YB:YAB CRYSTAL

The nonradiative transition fees follow the system WNR = W (0) exp(-alphap), the place p is the number of phonons matching the Electrical power gap. The nonradiative changeover costs of Er3+ show temperature dependence in line with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative peace charges is difficult because of
