The stimulated Raman gain spectrum of optical fibers has been measured down to 6 cm−1 by means of short pulses. Results for parallel and perpendicular polarizations are reported. With this technique, we observe spectral oscillations arising from a Brillouin mediated coupling between cw and pulsed light.
