- 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.
Analog / digital electronics
Instrumentation, piloting of atomic physics experiments (python language)
The candidate will integrate the OHMS group (http://teams.femto-st.fr/equipe-ohms/) at FEMTO-ST Time-Frequency department (www.femto-st.fr). The candidate should enjoy applied physics sciences, high-precision measurements, optics, electronics and instrumentation. A background in atomic physics and mechanical design is an actual plus-value.
The candidate will evolve in a group composed of researchers, engineers and technicians, will benefit from electronics, mechanics and computing services of FEMTO-ST and of a high-level time-frequency metrology platform (http://oscillatorimp.com/dokuwiki/doku.php). The candidate will present his/her work in international conferences and will aim to publish in high-impact scientific journals.
