A SECRET WEAPON FOR ER:YB:YAB CRYSTAL

The nonradiative changeover rates Keep to the formula WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the energy gap. The nonradiative changeover prices of Er3+ show temperature dependence in line with the multiphonon leisure theory. In Tm3+ the temperature dependence of nonradiative rest fees is difficult via the existence o
