摘要：
The absorption spectrum of Pr3+ and Pr3++Yb3+, the fluoresce wavelength of Pr3+ in ZBLAN glass have been measured. The energy transfer process in the Pr3+/Yb3+ co-doped fiber amplifier has been analyzed, and the probability of energy transfer between Pr3+ and Yb3+ has also been calculated using by electric multi-pole interaction theory. By discussing the energy transfer rate related to the rare-earth ion concentration and the pump wavelength, the best concentration and pump wavelength are obtained for the optimised fluores cenee at 1.3 μm and the most efficient gain of fiber amplifier.
