Benchmark measurements of absolute frequencies and collisional line-shape parameters in the CO-Ar system using comb-based FTS
Akiko Nishiyama, Grzegorz Kowzan, Dominik Charczun +2
We report absolute frequency measurements of the CO fundamental band, together with high-precision Ar-induced collisional line-shape parameters using comb-based Fourier-transform s…

Size characterization of neutral rare-gas clusters based on time-resolved polarization anisotropy measurements
Arne Morlok, Grzegorz Kowzan, Ulrich Bangert +3
The size determination of neutral clusters is experimentally challenging. In particular, weakly-bound rare-gas clusters tend to fragment upon ionization, resulting in systematic er…

Cavity-enhanced spectroscopy in the deep cryogenic regime -- new hydrogen technologies for quantum sensing
Kamil Stankiewicz, Marcin Makowski, MichaÅ SÅowiÅski +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…
