Measuring molecular frequencies in the 1--10 μm range at 11-digits accuracy
G. Insero, S. Borri, D. Calonico +7
Mid infrared (MIR) photonics is a key region for molecular physics [1]. High-resolution spectroscopy in the 1--10 μm region, though, has never been fully tackled for the lack of wi…

Frequency metrology of helium around 1083 nm and determination of the nuclear charge radius
P. Cancio Pastor, L. Consolino, G. Giusfredi +4
We measure the absolute frequency of seven out of the nine allowed transitions between the 2{\it S} and 2{\it P} hyperfine manifolds in a metastable He beam by using an…
