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…
Cavity-enhanced spectroscopy in the deep cryogenic regime -- new hydrogen technologies for quantum sensing
Kamil Stankiewicz, Marcin Makowski, Michał Słowiński +13
Spectrometers based on high-finesse optical cavities have proven to be powerful tools for applied and fundamental studies. Extending this technology to the deep cryogenic regime is…
Heterodyne dispersive cavity ring-down spectroscopy exploiting eigenmode frequencies for high-fidelity measurements
Agata Cygan, Szymon Wójtewicz, Hubert Jóźwiak +6
Measuring low light absorption with combined uncertainty < 1 permille is crucial in a wide range of applications. Popular cavity ring-down spectroscopy can provide ultra-high preci…
Engineering the sensitivity of macroscopic physical systems to variations in the fine-structure constant
Beata Zjawin, Marcin Bober, Roman Ciuryło +3
Experiments aimed at searching for variations in the fine-structure constant are based on spectroscopy of transitions in microscopic bound systems, such as atoms and ions, or r…
Sub-promille measurements and calculations of CO (3--0) overtone line intensities
K. Bielska, A. A. Kyuberis, Z. D. Reed +11
Intensities of lines in the near-infrared second overtone band (3--0) of CO are measured and calculated to an unprecedented degree of precision and accuracy. Agreemen…
