An infrared high-brightness light source based on supercontinuum generation through a SF6 photonic crystal fiber seeded by a Cr4+:YAG femtosecond oscillator is developed for high resolution multiplex spectroscopy in the 1.5 m region. Moreover, a multiplex high resolution approach based on a Cr4+:YAG frequency comb enables to probe large spectral domains, with simultaneous sensitive measurement of the absorption and the dispersion associated with all individual spectral features.
