A SIMPLE KEY FOR ER:YB:YAB CRYSTAL UNVEILED

The nonradiative changeover charges Adhere to the method WNR = W (0) exp(-alphap), in which p is the volume of phonons matching the Vitality hole. The nonradiative changeover prices of Er3+ exhibit temperature dependence per the multiphonon relaxation theory. In Tm3+ the temperature dependence of nonradiative rest charges is sophisticated from the
