High-speed measurement confronts the extreme speed limit when the signal becomes
comparable to the noise level. In the context of broadband mid-infrared spectroscopy, state …

Mid-infrared (MIR) spectrometers are invaluable tools for molecular fingerprinting and hyper-
spectral imaging. Among the available spectroscopic approaches, GHz MIR dual-comb …

The extension of dual-comb spectroscopy (DCS) to all wavelengths of light along with its
ability to provide ultra-large dynamic range and ultra-high spectral resolution, renders it …

We present a fast-scanning Fourier transform spectrometer (FTS) in combination with high-
repetition-rate mid-infrared supercontinuum sources, covering a wavelength range of 2–10.5 …

This Letter presents a 0.4–5.2-µm frequency comb from a compact laser. We designed an
integrated fiber device for a figure-9 laser and constructed an all-fiber laser system. The …

Open‐path dual‐comb spectroscopy provides multispecies atmospheric gas concentration
measurements with high precision. Here, open‐path dual‐comb spectroscopy is extended to …

In this Letter, we investigate steady states of fiber lasers mode-locked with a nonlinear
amplifying loop mirror that have an inherent amplitude-noise-suppression mechanism. Due …

Dual-comb spectroscopy (DCS) has been an emerging spectrometric technique with high
resolution, high sensitivity, broad spectral range and fast acquisition speed. However, it is …

Providing an accurate, representative sample of mass flux across large open areas for
atmospheric studies or the extreme conditions of a hypersonic engine is challenging for …

Detection of airborne chemical releases in densely populated urban environments requires
precise sensors with high temporal and spatial resolution capable of covering large areas …
