THE BEST SIDE OF ER:YB:YAB CRYSTAL

The nonradiative changeover fees Adhere to the method WNR = W (0) exp(-alphap), in which p is the number of phonons matching the Electrical power gap. The nonradiative changeover premiums of Er3+ exhibit temperature dependence according to the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative peace rates is challenging
