Abstract: Terahertz (THz) frequency combs are innovative tools for broadband THz spectroscopy because a series of comb modes can serve as frequency markers that are traceable to a frequency standard. However, usual THz spectrometer cannot resolve each mode of THz comb due to insufficient spectral resolution. Recently, dual THz comb spectroscopy appears as a new spectroscopic tool to acquire the mode-resolved THz comb spectrum with high resolution, high accuracy, broad spectral range, and moderate data acquisition time. In this paper, we have reviewed the recent progress of dual THz comb spectroscopy in our group.
