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

The nonradiative changeover charges Adhere to the components WNR = W (0) exp(-alphap), wherever p is the number of phonons matching the Electrical power gap. The nonradiative transition premiums of Er3+ show temperature dependence in step with the multiphonon leisure theory. In Tm3+ the temperature dependence of nonradiative relaxation prices is in
