THE 2-MINUTE RULE FOR ER:YB:YAB CRYSTAL

The nonradiative changeover prices Stick to the formula WNR = W (0) exp(-alphap), in which p is the quantity of phonons matching the Power hole. The nonradiative changeover charges of Er3+ show temperature dependence consistent with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative relaxation costs is complex because
