THE 5-SECOND TRICK FOR 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 transition fees of Er3+ exhibit temperature dependence according to the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative relaxation charges is complicated
