Cavity-Ring-Down Spectroscopy on theb1Σ+g–X3Σ−g(1,0) Band of Oxygen Isotopomers

Cavity-ring-down spectroscopy on the oxygen A band in magnetic fields up to 20 T

Line mixing and collision induced absorption in the oxygen A-band using cavity ring-down spectroscopy.

This paper reports on the absorption of molecular oxygen in the region of the A-band near 760 nm under atmospheric conditions relevant for satellite retrieval studies. We use pulsed laser cavity ring-down spectroscopy with a narrow bandwidth laser and use pressure scans to increase the accuracy of the measured oxygen extinction coefficients. Absolute binary absorption coefficients in minima bet...

Cavity-locked ring-down spectroscopy

Saturated-absorption cavity ring-down spectroscopy.

We report on a novel approach to cavity ring-down spectroscopy with the sample gas in saturated-absorption regime. This technique allows us to decouple and simultaneously retrieve the empty-cavity background and absorption signal, by means of a theoretical model that we developed and tested. The high sensitivity and frequency precision for spectroscopic applications are exploited to measure, fo...

An Introduction to Cavity Ring-Down Spectroscopy

Spectroscopy, the study of the interaction of light (electromagnetic radiation) and matter, is the most ubiquitous and precise method available to the physical scientist. Especially for isolated atoms, molecules, and small clusters, it has no peer. It is used to elucidate the structure and dynamics of quantum systems from atomic nuclei to natural proteins. Essentially everything we know about t...
