THE BEST SIDE OF ER:YB:YAB CRYSTAL

The nonradiative transition prices follow the formulation WNR = W (0) exp(-alphap), the place p is the number of phonons matching the energy hole. The nonradiative changeover fees of Er3+ show temperature dependence according to the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative relaxation fees is challenging via
