THE 5-SECOND TRICK FOR ER:YB:YAB CRYSTAL

The nonradiative changeover prices Adhere to the formula WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the Power hole. The nonradiative changeover charges of Er3+ show temperature dependence in line with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative rest fees is difficult via the existence
