Combining intracavity laser spectroscopy and step-scan time-resolved Fourier transform spectroscopy enables to get high sensitivity molecular laboratory spectra, exhibiting kilometric absorption paths. Specific advantages of the method, especially for frequency and intensity metrology of weak absorption transitions, are illustrated and discussed.
