Optical frequency combs (Nobel 2005) are pulsed-lasers which have been tailored for very precise frequency measurements. Whereas in most measurements involving combs, a continuous-wave laser perform spectroscopic probing of a sample, and the comb is only used to measure this cw-laser’s frequency, in Direct Frequency Comb Spectroscopy, we cut the middle man, and probe the samples with the light from the pulsed laser itself, raising remarkable opportunities as well as specific challenges.

The internship, based on existing components and know-how (lasers, frequency combs, low-noise electronics, data processing hardware and software), will consists in setting up various experimental configurations suitable for such approach, study the fundamental limits, and participate in the development of novel techniques (data acquisition and signal processing) aimed at improving sensitivity, versatility and ease-of-use (for in-field application) of the system. Application to probing various samples, mostly in dilute gas phase, will be carried on as a proof-of-principle experiments.

This internship is a great opportunity to learn advanced techniques in light-matter interaction, signal processing and high precision measurement, which are valuable knowledge in any king of deep-tech development (academic or private sector alike), as well a have a first-hand approach of cutting-edge fundamental research.
