THE BEST SIDE OF ER:YB:YAB CRYSTAL

The nonradiative changeover fees follow the formulation WNR = W (0) exp(-alphap), exactly where p is the quantity of phonons matching the energy hole. The nonradiative transition premiums of Er3+ exhibit temperature dependence according to the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative leisure charges is difficult
