ER:YB:YAB CRYSTAL OPTIONS

The nonradiative changeover fees Keep to the formulation WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the energy gap. The nonradiative changeover fees of Er3+ exhibit temperature dependence in keeping with the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative rest premiums is complicated thr
