By reducing both the internal and translational temperature of any species down to a few
kelvins, the buffer-gas-cooling (BGC) technique has the potential to dramatically improve the …

This article provides an overview of laser-based absorption spectroscopy applications and
discusses the parameter space and requirements of laser systems for each of these …

Lamb dips of twenty lines in the P, Q, and R branches of the ν1+ ν3+ ν41 vibrational band of
12C2H2, in the spectral window of 7125–7230 cm− 1, have been measured using an …

Cavity-enhanced spectroscopic techniques are highly sensitive laser-based methods for
interrogating the atomic and molecular constituents of any gaseous medium that is confined …

A non-linear spectroscopic study of the HDO molecule is performed in the wavelength range
of 1.36–1.42 μm using noise-immune cavity-enhanced optical-heterodyne molecular …

Cross-sensitivity limits accurate quantitative detection of species concentrations in all sensor

Accurate spectroscopic data of carbon dioxide are widely used in many important
applications, such as carbon monitoring missions. Here, we present comb-locked cavity ring …

We report a method of efficiently generating ultracold hydrogen molecular ions HD+ in a
segmented linear ion trap. HD+ ions are created by [2+ 1′] resonance-enhanced …

Silver-based chalcogenide semiconductors exhibit low toxicity and near-infrared optical
properties and are therefore extensively employed in the field of solar cells, photodetectors …

This research focused on conducting high-resolution spectroscopy on water and deuteride
hydrogen molecules, with a particular emphasis on measuring various isotopologues. The …
