The causal mechanisms responsible for the abrupt climate changes of the Last Glacial Period
remain unclear. One major difficulty is dating ice-rafted debris deposits associated with …

Until now, applications of cavity ring down spectroscopy (CRDS) employed pulsed laser
sources. Here, we demonstrate that a commercial single-frequency CW laser can also be …

Cavity ring‐down is becoming a widely used technique in gas phase spectroscopy. It holds
promise for further important extensions, which will lead to even more frequent use. However…

We study the response of a high-finesse optical cavity to a cw laser during the laser frequency
passage through resonance. For a laser that is spectrally larger than the cavity resonance, …

In this introductory chapter we will begin with an historical outline of the development of
cavity enhanced absorption methods, with just enough attention to the applications that either …

Ancient air trapped inside bubbles in ice cores can now be analysed for methane concentration
utilising a laser spectrometer coupled to a continuous melter system. We present a new …

Detection and analysis of volatile compounds in exhaled breath represents an attractive tool
for monitoring the metabolic status of a patient and disease diagnosis, since it is non-…

We demonstrate the principle of cavity enhanced absorption with femtosecond modelocked
lasers. The wide spectral coverage allowed by these sources makes this a promising high??…

We introduce PyVertical, a framework supporting vertical federated learning using split neural
networks. The proposed framework allows a data scientist to train neural networks on data …

The absorption spectrum of natural water vapour around 1.5μm has been recorded with a
typical sensitivity of 5×10 −10 cm −1 by using a CW-cavity ring down spectroscopy set up …
