ER:YB:YAB CRYSTAL - AN OVERVIEW

The nonradiative changeover rates Adhere to the formulation WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the energy gap. The nonradiative changeover fees of Er3+ exhibit temperature dependence per the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative leisure premiums is complicated through the exi
