“…In addition, a lot of efforts have been made in dual-comb fiber laser with SWNT SAs by Zheng et al since 2012 [265]. In the last few years, driven by the increasing attractiveness of low-complexity multicomb in the field of spectroscopy, frequency and distance measurement, they have reported dualcomb, tricomb and even quad-comb generation from a simple single-cavity mode-locked fiber laser with an SWNT SA by leveraging simultaneous multiplexing in wavelength and polarization [266,267]. Based on the rapid development of fiber frequency comb technology, we believe that the all-fiber frequency comb system using an SWNT SA brings a broad prospect as a robust, portable, cost-effective and highperformance fiber frequency comb.…”

Carbon nanotubes (CNTs) possess remarkable nonlinear optical properties; a particular application is to function as a mode locker used in ultrafast fiber lasers to produce ultrashort optical pulses. Various types of CNT saturable absorbers (SAs) and ultrafast fiber lasers have been demonstrated. In this review, typical fabrication process and development of CNT SAs are discussed and we highlight the recent investigation and progress of state-of-the-art ultrafast fiber lasers covering GHz, bidirectional ultrafast fiber lasers, vectorial mode fiber lasers, comb systems, and mode-locking dynamics. Our perspectives of ultrafast fiber lasers based on CNT SAs are given finally.

“…THz-DCS systems and optical DCS systems. Recently, advances in the endeavor to generate a pair of frequency combs from a free-running single-cavity laser [22][23][24][25][26][27][28][29][30][31] have shown great potential towards this goal. By propagating through the same cavity, the dual optical combs experience almost the same disturbances, and the commonmode fluctuations thereby prevent the decline of the mutual coherence between the dual combs.…”

Mode-resolved dual-comb spectroscopy (DCS) is an emerging spectroscopic tool with the potential to simultaneously achieve a broad spectral coverage and ultrahigh spectral resolution in terahertz (THz) spectroscopy. However, the need for two independently stabilized ultrafast lasers significantly hampers the potential application of DCS techniques. In this article, we demonstrate mode-resolved DCS in the THz region based on a free-running single-cavity dual-comb fiber laser with adaptive sampling. Low-pressure spectroscopy of acetonitrile gas with absorption features approaching the Doppler limit is demonstrated by comb-mode-resolved measurements with a spectral sampling spacing of 48.8 MHz, a spectral resolution of less than 5 MHz and a signal-to-noise ratio of ~50 dB. The successful demonstration of the proposed method clearly indicates the great potential for the realization of lowcomplexity, MHz-resolution THz spectroscopy instrumentation.

Dual-comb spectroscopy (DCS) is an emerging spectroscopic tool with the potential to simultaneously achieve a broad spectral coverage and ultrahigh spectral resolution with rapid data acquisition. However, the need for two independently stabilized ultrafast lasers significantly hampers the potential application of DCS. We demonstrate mode-resolved DCS in the THz region based on a free-running singlecavity dual-comb fiber laser with the adaptive sampling method. While the use of a free-running single-cavity dual-comb fiber laser eliminates the need for two mode-locked lasers and their frequency control, the adaptive sampling method strongly prevents the degradation of spectroscopic performance caused by the residual timing jitter in the free-running dual-comb laser. Doppler-limit-approaching absorption features with linewidths down to 25 MHz are investigated for low-pressure acetonitrile/air mixed gas by comb-mode-resolved THz spectroscopy. The successful demonstration clearly indicates its great potential for the realization of lowcomplexity, Doppler-limited THz spectroscopy instrumentation.
