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

The nonradiative changeover fees Keep to the formula WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the Electrical power gap. The nonradiative transition premiums of Er3+ show temperature dependence in step with the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative relaxation premiums is difficult
