We present the application of Optical Frequency Comb (OFC) to cavity-enhanced spectroscopies, such as cavity enhanced absorption spectroscopy (CEAS), cavity mode-width spectroscopy (CMWS), and cavity mode dispersion spectroscopy (CMDS). These spectroscopies realize highly sensitive spectral acquisition over the broadband OFC spectrum, and provide instrumental-line-shape-free spectra for accurate molecular line-shape studies.
