TOP GUIDELINES OF ER:YB:YAB CRYSTAL

The nonradiative changeover costs follow the components WNR = W (0) exp(-alphap), the place p is the number of phonons matching the Electricity gap. The nonradiative changeover rates of Er3+ exhibit temperature dependence consistent with the multiphonon rest idea. In Tm3+ the temperature dependence of nonradiative rest premiums is difficult because
