【 摘 要 】

We describe the development of an optical lattice clock based on mercury and the results obtained since the 7thSFSM. We briefly present a new solution for the cooling laser system and an improved lattice trap that allows us to interrogate a few thousand atoms in parallel. This translates into a fractional short term stability of 1.2 x 10-15at the clock frequency of 1.129 PHz.
