WHAT DOES ER:YB:YAB CRYSTAL MEAN?

The nonradiative changeover rates Keep to the formula WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the Electrical power hole. The nonradiative changeover fees of Er3+ exhibit temperature dependence consistent with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative rest premiums is challengin
