ER:YB:YAB CRYSTAL OPTIONS

The nonradiative changeover premiums Keep to the formula WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the Vitality gap. The nonradiative changeover rates of Er3+ show temperature dependence per the multiphonon peace principle. In Tm3+ the temperature dependence of nonradiative relaxation rates is complicated through the ex
