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.
