Vortex-comb spectroscopy
Santeri Larnimaa, Markku Vainio
We propose a new Fourier-transform spectroscopy technique based on the rotational Doppler effect. The technique offers an application for optical vortex frequency combs, where each…
Reference-free dual-comb spectroscopy with inbuilt coherence
Mikhail Roiz, Santeri Larnimaa, Touko Uotila +2
We demonstrate a simple system for dual-comb spectroscopy based on two inherently coherent optical frequency combs generated via seeded parametric down-conversion. The inbuilt cohe…
Photoacoustic phase-controlled Fourier-transform infrared spectroscopy
Santeri Larnimaa, Mikhail Roiz, Markku Vainio
We demonstrate a 13-fold speed improvement in broadband cantilever-enhanced photoacoustic spectroscopy (CEPAS) by combining it with phase-controlled Fourier-transform spectroscopy…
Infrared spectroscopy of radioactive hydrogen chloride HCl
Santeri Larnimaa, Markku Vainio, Ville Ulvila
We present the first report of optical absorption spectroscopy of HCl, a radioactive isotopologue of hydrogen chloride. We used Fourier-transform infrared spectroscopy to…
High-resolution analysis of the band of radiocarbon methane
Santeri Larnimaa, Lauri Halonen, Juho Karhu +6
We present the first high-resolution measurements and rotational analysis of the fundamental asymmetric stretching vibrational band of radiocarbon methane. A spectrome…
