THE BEST SIDE OF ER:YB:YAB CRYSTAL

The nonradiative changeover fees follow the system WNR = W (0) exp(-alphap), exactly where p is the number of phonons matching the Vitality hole. The nonradiative changeover fees of Er3+ show temperature dependence consistent with the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative relaxation charges is intricate becaus
