We report on the measurement of the Raman gain coefficient in a standard single mode optical fibre (SMF), based on the power transfer between a high intensity pump signal and a counter-propagated broadband probe signal technique. The results were complemented with spontaneous Raman spectroscopy. The values of 7.48×10–27 mW–1Hz–1, 0.540×10–13 mW–1, 3.03 fs, 12.40 fs, 40.78 fs and 0.160 were experimentally obtained for the Raman gain slope, maximum value of the gain coefficient, Raman time constant, first and second parameters of the Raman response function and fractional contribution of the delayed Raman response, respectively.
