Abstract :
We fully interpolated frequency gaps between THz comb modes by tuning mode-locked frequencies in dual fiber lasers used for generation and detection of THz comb. The resulting gapless THz comb implies a possibility to enhance the spectral resolution in THz spectroscopy down to the linewidth of each comb mode.
