Accounting for the detection response brings cavity ring-down spectroscopy to sub-permille accuracy
Rajesh Chell, Marcin Gibas, Szymon Wójtewicz +3
For nearly four decades, cavity ring-down spectroscopy (CRDS) has been among the simplest, most widely used absorption techniques, requiring no calibration because it measures deca…
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…
Stimulated-Raman-Scattering Metrology
M. Lamperti, L. Rutkowski, D. Ronchetti +10
Frequency combs have revolutionized optical frequency metrology, allowing one to determine highly accurate transition frequencies of a wealth of molecular species. Despite a recogn…
Measurement of electron-calcium ionization integral cross section using an ion trap with a low-energy, pulsed electron gun
Łukasz Kłosowski, Mariusz Piwiński, Szymon Wójtewicz +1
An apparatus for production of various atomic and molecular ions inside a linear Paul trap has been set up. The system applies a custom-made, low energy, pulsed electron gun to pro…
