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. %K Fiber optics %K Nonlinear optics %K Slow light %K Gas sensing %K Stimulated Brillouin scattering %K Ciencias tecnológicas %K Electrónica %K Technology %K Electronics %~ Biblioteca Universidad de Alcala
