Cavity Ring-Down Spectroscopy at Benchmark-Level Sub-Permille Accuracy Enabled by a System-Level Detection Transfer Function
Rajesh Chell, Marcin Gibas, Szymon Wójtewicz +3
Cavity ring-down spectroscopy (CRDS) is widely used for sensitive optical absorption measurements, but its quantitative accuracy can be limited at the few-percent level by systemat…

Leveraging resonant frequencies of an optical cavity for spectroscopic measurement of gas temperature and concentration
Daniel Lisak, Vittorio D'Agostino, Szymon Wójtewicz +5
We introduce a spectroscopic approach to primary gas thermometry, harnessing precise optical cavity resonance frequencies and ab initio molecular line intensity calculations. By ut…
