THE BASIC PRINCIPLES OF ER:YB:YAB CRYSTAL

The nonradiative changeover prices Stick to the method WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the Strength hole. The nonradiative changeover costs of Er3+ exhibit temperature dependence in line with the multiphonon relaxation theory. In Tm3+ the temperature dependence of nonradiative relaxation charges is sophisticate
