THz frequency comb, composed of a series of frequency spike regularly spaced by a repetition frequency, can be used as a precise and accurate frequency marker for broadband THz spectroscopy because it can be phase-locked to a microwave frequency standard by laser control. The mode-resolved THz comb spectrum is obtained by dual  comb technique and applied for low-pressure gas spectroscopy.
