NOT KNOWN DETAILS ABOUT ER:YB:YAB CRYSTAL

The nonradiative changeover rates Adhere to the components WNR = W (0) exp(-alphap), the place p is the number of phonons matching the Strength hole. The nonradiative transition charges of Er3+ show temperature dependence in line with the multiphonon leisure principle. In Tm3+ the temperature dependence of nonradiative peace fees is challenging via
