There is an increasing demand for precise molecular spectroscopy, in particular in the mid-
infrared (MIR) fingerprint window that hosts a considerable number of vibrational signatures …

An optical-frequency-comb-referenced quantum cascade laser is used to perform
wavelength-modulation Lamb-dip spectroscopy on a large number of ro-vibrational …

The thesis consists in developing a high-resolution mid-infrared spectrometer traceable to
primary frequency standards and providing a unique combination of resolution, tunability …

Nous avons développé deux spectromètres moyen infrarouge (MIR) qui combinent très
haute résolution, accordabilité, sensibilité de détection et contrôle de la fréquence absolue …

This doctoral dissertation presents different approaches to exploit optical frequency comb
sources for high precision and broadband spectroscopy. In particular, a comb assisted sub …
