HELPING THE OTHERS REALIZE THE ADVANTAGES OF ER:YB:YAB CRYSTAL

The nonradiative transition charges follow the system WNR = W (0) exp(-alphap), the place p is the number of phonons matching the energy hole. The nonradiative changeover rates of Er3+ exhibit temperature dependence consistent with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative leisure fees is difficult because o
