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…
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…
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…
Absolute frequency determination of molecular transition in the Doppler regime at kHz level of accuracy
K. Bielska, S. Wojtewicz, P. Morzynski +7
We present absolute frequency measurement of the unperturbed P7 P7 O B-band transition with relative standard uncertainty of . We reached the level of accuracy…
High accuracy CO line intensities determined from theory and experiment
Oleg L. Polyansky, Katarzyna Bielska, Mélanie Ghysels +4
Atmospheric CO concentrations are being closely monitored by remote sensing experiments which rely on knowing line intensities with an uncertainty of 0.5\%\ or better. Most ava…
Strontium optical lattice clocks for practical realization of the metre and secondary representation of the second
M. Bober, P. Morzyński, A. Cygan +17
We present a system of two independent strontium optical lattice standards probed with a single shared ultra-narrow laser. The absolute frequency of the clocks can be verified by t…
Buffer gas induced collision shift for the Sr clock transition
Nobuyasu Shiga, Ying Li, Hiroyuki Ito +5
Precision saturation spectroscopy of the is performed in a vapor cell filled with various rare gas including He, Ne, Ar, and Xe. By continuously calibra…
