A SECRET WEAPON FOR ER:YB:YAB CRYSTAL

The nonradiative changeover fees Adhere to the formula WNR = W (0) exp(-alphap), in which p is the quantity of phonons matching the Vitality hole. The nonradiative changeover charges of Er3+ show temperature dependence consistent with the multiphonon relaxation theory. In Tm3+ the temperature dependence of nonradiative rest premiums is difficult be
