Abstract
The upconversion quantum efficiency and power-conversion efficiency in Tb3+-Yb3+ codoped glass have been investigated theoretically by the cooperative sensitization rate equation model. Both efficiencies exhibited linear relations with pump-power density and decreased with Yb3+ concentration. It was found that the ratio of quantum efficiency to power-conversion efficiency is constant (0.56) and independent of pump-power density and Yb3+ concentration. The theoretical predictions were confirmed by the experimental results measured by an integrating sphere system. The absolute upconversion efficiency was estimated to be on the order of 10-4 in the pump-power density range of 40-96 W/cm2.
