摘    要:The energy transfer and cooperation upconversion processes are investigated in Yb3+/Er3+ codoped phos- phate glass. Based on the measured curves of output power versus incident power, the laser and spectroscopic parameters of the glass are fitted and analyzed. We focus on the resonant energy transfer constant k from Yb3+ to Er3+ as well as the cooperation upconversion coefficient Cup from 4113/2 of Era+. The fitted k and Cup can give almost the same results for different thicknesses of glass disk with the same dop- ing concentrations. The determination of these parameters is helpful for the development of Yb3+/Er3+ codoped laser glass.
