Iodine frequency stabilized laser for ground tests of LISA mission

20 August 2020

An all-fibered frequency-stabilized laser source device whose volume does not exceed 30 liters is being developed at SYRTE by the optical frequency metrology team. This device consists of a telecom C-band laser source at 1.5 µm (near IR) supplemented by an original frequency tripling device developed and patented by SYRTE. The device is then associated with a molecular transition of iodine to 515 nm (green) which serves as a frequency reference.
DISHAS is online!

20 July 2020

The web application DISHAS (Digital Information System for the History of Astral Sciences) is operational since the end of May 2020.

After four years of modeling and development work within an international team led by SYRTE, it starts to receive its first historical data.

First Two-Way Satellite Link with Digital Reception in UTC

18 March 2020

For the first time, Two-Way Satellite Time and Frequency Transfer between LNE-SYRTE and PTB, improved by Software-Defined Radio solution, is used for International Atomic Time (TAI) and Coordinated Universal Time (UTC) computations.
a new way to search for a variation of the fine-structure constant

26 February 2020

For the first time, spectral measurements of five stars orbiting the supermassive black hole in our Galactic Center leads to a direct constraint on a possible variation of the fine structure constant.

It is a leader in time and frequenciy metrology and is also specialized in Earth rotation, celestial reference frame and history of Astronomy.
SYRTE has a multidisciplinary research activity with transverse expertise in theory, instrumentation and data analysis and various goals from fundamental physics tests to industrial transfers.It is founder membre of Laboratoire d’Excellence du Programme Investissements d’Avenir FIRST-TF.

It has in charge several international services. Associated with the LNE - Laboratoire National de Métrologie et d’Essais - the SYRTE has the responsability of the national reference time and frequence. With the IERS (International Earth Rotation Service), it deliver Earth rotation parameters and other services.

Its teams take part in training and education by giving university lectures and also spread scientific culture by organizing public talks.
