23. As noted in Ref. 1, forward Raman scattering (FRS) of the amplified seed may also limit the amplification length. Since the growth times of FRS and modulational instabilities are roughly comparable in the regime of interest and since FRS may be stabilized by the introduction of a weak density gradient (Ref. 19) (as considered in Sec. III), for simplicity the amplification length is taken here to be constrained only by the modulational instability. Generalization to include the constraint of FRS, however, would be straightforward.
24. Chirping of the pump frequency would have an effect similar to that of a density gradient on the resonance. By properly defining q, the following results could also be applied to this case (Ref. 2).
25. References 20 and 21 have pointed out that there are many misprints/errors in Ref. 9. Though the essential results are correct, the supporting formulas must be used cautiously.
26. This result was first noticed by seeking a solution of Eqs. (5) explicitly in terms of η (Ref. 22).
