Optical frequency combs were developed nearly two decades ago to support the world's
most precise atomic clocks. Acting as precision optical synthesizers, frequency combs …

Dual-comb spectroscopy is an emerging new spectroscopic tool that exploits the frequency
resolution, frequency accuracy, broad bandwidth, and brightness of frequency combs for …

The HITRAN database is a compilation of molecular spectroscopic parameters. It was
established in the early 1970s and is used by various computer codes to predict and …

Mid-infrared spectroscopy offers supreme sensitivity for the detection of trace gases, solids
and liquids based on tell-tale vibrational bands specific to this spectral region. Here, we …

The development of high-power, broadband sources of coherent mid-infrared radiation is
currently the subject of intense research that is driven by a substantial number of existing …

Breath analysis enables rapid, noninvasive diagnostics, as well as long-term monitoring of
human health, through the identification and quantification of exhaled biomarkers. Here, we …

Accurate parameters of molecular hot-band transitions, ie, those starting from vibrationally
excited levels, are needed to accurately model high-temperature spectra in astrophysics and …

Nonlinear optical frequency conversion is one of the most versatile methods to generate
wavelength-tunable laser light in the mid-infrared region. This spectral region is particularly …
