ER:YB:YAB CRYSTAL CAN BE FUN FOR ANYONE

The nonradiative transition fees Keep to the formula WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the energy hole. The nonradiative changeover costs of Er3+ show temperature dependence in step with the multiphonon peace principle. In Tm3+ the temperature dependence of nonradiative relaxation costs is sophisticated from the
