A SECRET WEAPON FOR ER:YB:YAB CRYSTAL

The nonradiative transition premiums Keep to the components WNR = W (0) exp(-alphap), where by p is the volume of phonons matching the Vitality gap. The nonradiative transition premiums of Er3+ exhibit temperature dependence in step with the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative relaxation prices is complex wi
