International audienceSupercontinua generated in highly non-linear fibers by ultrashort-pulse lasers can be used for high resolution Fourier transform absorption spectroscopy. The practical advantages of these bright ultrabroadband light sources for spectroscopy are reported in the near-infrared region. A Cr^4+:YAG femtosecond laser broadened by an extruded soft-glass photonic crystal fiber, emitting from 1200 to 2200 nm and from 675 to 950 nm, provides a spectral radiance being 1x10^5 times higher than that of a 3000 K blackbody and 10^2 times higher than that of a synchrotron radiation. The C_2H_2 and NH_3 overtone spectra are recorded using this source within a few seconds
