THE BEST SIDE OF ER:YB:YAB CRYSTAL

The nonradiative changeover rates Adhere to the method WNR = W (0) exp(-alphap), exactly where p is the amount of phonons matching the Electrical power gap. The nonradiative transition costs of Er3+ show temperature dependence according to the multiphonon leisure theory. In Tm3+ the temperature dependence of nonradiative peace fees is sophisticated
