Expérimental Description
Optical lattice clocks have reached such a resolution that they can now be controlled at the 18 digits level. This makes them able to detect a change of height of 1 cm, via a general relativity effect called gravitational time dilation. At SYRTE, Observatoire de Paris, we are building a transportable Ytterbium lattice clock, targeting ultrahigh stability, in order to participate to the cartography of the geopotential in the future. The M2 student will work on the construction of a new 399 nm laser source and the design of a moving optical molasses at this wavelength, in order to reach ultrafast trapping of ytterbium 171 atoms.
