THE BASIC PRINCIPLES OF ER:YB:YAB CRYSTAL

The nonradiative transition prices follow the formulation WNR = W (0) exp(-alphap), where p is the volume of phonons matching the Strength hole. The nonradiative transition charges of Er3+ show temperature dependence according to the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative relaxation charges is sophisticated fro
