NOT KNOWN DETAILS ABOUT ER:YB:YAB CRYSTAL

The nonradiative changeover premiums Stick to the components WNR = W (0) exp(-alphap), exactly where p is the quantity of phonons matching the Power gap. The nonradiative changeover costs of Er3+ exhibit temperature dependence in step with the multiphonon rest idea. In Tm3+ the temperature dependence of nonradiative peace prices is difficult from t
