THE DEFINITIVE GUIDE TO ER:YB:YAB CRYSTAL

The nonradiative transition prices Adhere to the method WNR = W (0) exp(-alphap), exactly where p is the volume of phonons matching the energy gap. The nonradiative changeover prices of Er3+ show temperature dependence in line with the multiphonon rest idea. In Tm3+ the temperature dependence of nonradiative relaxation charges is complicated throug
