THE BEST SIDE OF ER:YB:YAB CRYSTAL

The nonradiative changeover charges follow the components WNR = W (0) exp(-alphap), where by p is the quantity of phonons matching the Vitality hole. The nonradiative transition premiums of Er3+ exhibit temperature dependence in step with the multiphonon leisure concept. In Tm3+ the temperature dependence of nonradiative relaxation premiums is diff
