Syrte, Obervatoire de Paris, CNRS
The SYRTE department - Sytèmes de Référence Temps Espace - belongs to Observatoire de Paris - Université PSL and is also associated with the CNRS (National Research Center), the Sorbonne Université and the LNE.
Syrte is a leader in time and frequency metrology and is also specialized in Earth rotation, celestial reference frame and history of Astronomy. SYRTE has a multidisciplinary research activity with expertise in theory, instrumentation and data analysis and various goals from fundamental physics tests to industrial transfers. It is a founding member of Laboratoire d’Excellence du Programme Investissements d’Avenir FIRST-TF. The optical frequency metrology within Syrte has developed some of the most precise strontium optical lattice clocks in the world and in addition to the AQuRA project is developing a transportable ytterbium optical lattice clock. Within AQuRA, Syrte will lead the development of the strontium optical lattice clock physics package as well as play a key role in both the system design and the integration and validation of the AQuRA clock. |
Team members
Rodolphe Le Targat is staff researcher at SYRTE, Observatoire de Paris, since 2011. He leads frequency combs activities, together with the development of infrared ultrastable lasers at 1542 nm. He also coordinates the construction of a transportable optical lattice clock based on neutral ytterbium.

Dr. Haosen Shang graduated from Peking Univerisity and then joined the strontium optical lattice clock team of SYRTE, Observatoire de Paris as a postdoc fellow. His works are on promoting the performance of the optical lattice clocks, including the improvement of the frequency stability via quantum nondemolition measurements and accurate estimations of some dominant systematic factors for reducing the frequency measurement uncertainty. As a part of the team, he also makes yearly contributions to the TAI with the strontium clocks in SYRTE.
