We report the first observation to our knowledge of the saturation effect in a Raman transition of a liquid, liquid N2. Using cw coherent anti-Stokes Raman spectroscopy, Raman line broadening by a factor of ≃2 is observed. This corresponds to vibrational excitation of up to 30% of the N2 molecules in the interaction volume.
