Resumen
The absorption of light by a gas molecule has been measured comparatively using light propagating in normal conditions
and in a slow light regime. The experiment is designed to make the 2 measurements possible without modifying the
interaction conditions, so that the sole effect of slow light is unambiguously observed. A 26% group velocity reduction
induced by stimulated Brillouin scattering in a gas-filled microstructured fiber caused no observable change in the
measured absorption, so that it is proved that material slow light does not enhance Beer-Lambert absorption and has a
null impact on gas sensing or spectroscopic applications.
