Abstract
Recent interest in optical pulse compression, particularly at 1.06 μm, has resulted in several experimental1 and theoretical2 studies of the interaction of stimulated Raman scattering (SRS) and self-phase modulation (SPM) in polarization-preserving fiber. Similar work3 has been reported for shorter wavelengths. We shall discuss the Interaction of SRS with the self-phase modulated pump pulse using nonpolarization-preserving fiber at throughput powers of 1-4.5 W continuous. We observed, for the first time we believe, the generation of an SRS pulse at 1.082 μm which can be excited either alone or in tandem with the previously reported 1.12-μm SRS pulse. These pulses can exhibit exceptionally large spectral broadenings of 70 and 400 A, respectively, and may present an opportunity to generate extremely short pulses at these two wavelengths.
