- Contribution to the development of two lasers (895 nm) frequency-controlled on an alkaline vapor microcell by dual-frequency sub-Doppler spectroscopy
- Metrological characterization of the frequency stability performance of the servo lasers on microcell by beating between two identical lasers.
- Implementation of advanced interrogation protocols to reduce light displacement phenomena.
- Contribution to the generation and transfer of an ultra-stable 895 nm optical signal from a servo-ultrastable laser and femlo-second frequency comb Menlo Systems, available in the laboratory. This signal can be used as a frequency reference for measuring lasers controlled on a microcell.
- Collaboration / Supervision of a doctoral student working on experience (since October 2019).
- Contribution to the writing of articles presenting the results of the experiment.
