A REVIEW OF ER:YB:YAB CRYSTAL

The nonradiative changeover rates Adhere to the formulation WNR = W (0) exp(-alphap), exactly where p is the quantity of phonons matching the Electrical power gap. The nonradiative changeover prices of Er3+ show temperature dependence in keeping with the multiphonon relaxation theory. In Tm3+ the temperature dependence of nonradiative peace rates i
