NOT KNOWN FACTUAL STATEMENTS ABOUT ER:YB:YAB CRYSTAL

The nonradiative changeover fees Keep to the formula WNR = W (0) exp(-alphap), wherever p is the amount of phonons matching the Electrical power gap. The nonradiative changeover rates of Er3+ exhibit temperature dependence in keeping with the multiphonon relaxation theory. In Tm3+ the temperature dependence of nonradiative rest premiums is complica
