THE BEST SIDE OF ER:YB:YAB CRYSTAL

The nonradiative changeover charges Adhere to the method WNR = W (0) exp(-alphap), exactly where p is the quantity of phonons matching the Power gap. The nonradiative changeover fees of Er3+ exhibit temperature dependence according to the multiphonon rest concept. In Tm3+ the temperature dependence of nonradiative leisure charges is difficult becau
