THE BEST SIDE OF ER:YB:YAB CRYSTAL

The nonradiative transition costs Adhere to the method WNR = W (0) exp(-alphap), exactly where p is the volume of phonons matching the Vitality hole. The nonradiative transition costs of Er3+ show temperature dependence per the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative relaxation costs is difficult from the exis
