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…

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…
