Abstract

High power fiber laser amplifier cascade can be simplified using double-pass scheme due to improvement of overall efficiency, especially for amplifiers with small input seed or high stored energy. The yield of stimulated Raman scattering (SRS) in the double-pass scheme is comparable to the level in amplifiers using counter-directional-pumped single-pass scheme if the pumping configuration is appropriate, even though the interaction length becomes twice for double pass scheme. In the study, insertions of Raman strippers along the active fiber with double-pass scheme is proved to be another choice to effectively suppress SRS besides the utilization of photonic band-gap fibers.
