A REVIEW OF ER:YB:YAB CRYSTAL

The nonradiative transition rates Adhere to the formulation WNR = W (0) exp(-alphap), exactly where p is the volume of phonons matching the Vitality hole. The nonradiative transition fees of Er3+ exhibit temperature dependence in keeping with the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative rest premiums is com
