A SIMPLE KEY FOR ER:YB:YAB CRYSTAL UNVEILED

The nonradiative transition charges Stick to the formulation WNR = W (0) exp(-alphap), exactly where p is the volume of phonons matching the Strength hole. The nonradiative transition rates of Er3+ exhibit temperature dependence in keeping with the multiphonon rest theory. In Tm3+ the temperature dependence of nonradiative peace premiums is sophist
