Direct comb spectroscopy (DCS), a technique that utilizes a well-stabilized pulse train to study the spectral properties of atomic or molecular systems, opens a new era of spectroscopic measurements. DCS has been a topic of growing interest not only for studying the atomic and molecular structure and dynamics but also for applications in environmental and biomedical sciences. In this talk, I will present a novel DCS technique: Dual-comb spectroscopy, a multi-heterodyne Fourier transform spectroscopy based on two frequency combs at slightly different repetition frequencies, enables the simultaneous achievement of broadband, high-resolution, and rapid spectral measurement for molecular fingerprinting.
