Abstract
Supercontinua generated in highly nonlinear 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 in the near-infrared region are reported. A femtosecond laser broadened by an extruded soft-glass photonic crystal fiber, emitting from and from , provides a spectral radiance times higher than that of a blackbody and times higher than that of synchrotron radiation. The and overtone spectra are recorded by using this source within a few seconds.
