Abstract: In this paper, we investigate the suitability of two commonly used rare earth ions viz. Erbium and Ytterbium for building a solar pumped fiber amplifier. Based on the solar spectrum and the absorption cross section for the rare earth ions we find that the Ytterbium is more suitable since it has a larger net absorption over the solar spectrum.
