We review progress, since publication of the book``Collisional effects on molecular spectra:
Laboratory experiments and models, consequences for applications"(Elsevier, Amsterdam …

Cavity ring-down spectroscopy (CRDS) is a direct quantitative absorption technique that
utilizes an enhanced light-matter interaction length inside a high-finesse optical resonator …

Abstract The β-corrected Hartmann–Tran profile (HTP) constitutes an approximation of the
partially correlated quadratic speed-dependent billiard-ball profile (SDBBP) easily …

A simple approximation scheme to describe the half width of the Voigt profile as a function of
the relative contributions of Gaussian and Lorentzian broadening is presented. The …

We demonstrate broadband and sensitive cavity ring-down spectroscopy using a near
infrared frequency comb and a time-resolved Fourier transform spectrometer. The cavity …

This paper reports the implementation of Doppler-broadening gas thermometry by use of
line-shape analysis of a line-doublet. The two spectral components are vibration-rotation …

Laser-based primary thermometry was initiated almost 15 years ago by the proposal to
determine the absolute temperature of a gas at thermodynamic equilibrium through the …

We present a complex-valued electric field model for experimentally observed cavity
transmission in coherent cavity-enhanced (CE) multiplexed spectroscopy (ie, dual-comb …

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

Doppler-broadening gas thermometry is extended to the deep-ultraviolet domain using a
comb-locked laser frequency chain, expressly developed for precision spectroscopy of …
