CONSIDERATIONS TO KNOW ABOUT ER:YB:YAB CRYSTAL

The nonradiative transition fees Keep to the formula WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the Power hole. The nonradiative changeover prices of Er3+ show temperature dependence in line with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative relaxation prices is complicated by the exis
