THE ULTIMATE GUIDE TO ER:YB:YAB CRYSTAL

The nonradiative changeover rates Keep to the formulation WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the energy gap. The nonradiative transition premiums of Er3+ show temperature dependence per the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative leisure fees is difficult from the existen
