The objective of the in-fiber optical amplification work is to improve the recordability of fast, weak analog diagnostic signals by increasing their intensity. Linear amplification is achieved using the backward stimulated Raman scattering process in a fiber lightguide data link. Feasibility of this technique was experimentally demonstrated and reported last year. Further studies and investigations carried out recently have been aimed at development of a practical multichannel in-fiber amplification technique that will enable acquisition of weak single-transient pulses transmitted over kilometer-length data links. We report here the results of this work, including an interesting observation of enhanced bandwidth in the amplified, versus the unamplified, received signal. 1 ref., 5 figs.
