ER:YB:YAB CRYSTAL FOR DUMMIES

The nonradiative changeover charges Stick to the formula WNR = W (0) exp(-alphap), where p is the amount of phonons matching the Electrical power gap. The nonradiative transition fees of Er3+ exhibit temperature dependence according to the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative peace charges is complex becaus
