The rapid improvement in the performance of optical clocks are opening the door to new technological and scientific applications. Ultra-precise optical clocks in space will allow many experiments, as in the field of fundamental physics (Einstein’s gravitational time dilation), time and frequency metrology (comparison between ground clocks using a master clock in space), geophysics (space-assisted relativistic geodesy) and astronomy (local oscillators for radio ranging and interferometry in space). The ESA candidate mission Space Optical Clocks project aims at operating an optical lattice clock on the ISS in approximately 2022.
Within an EU-FP7-funded project, a compact and robust strontium optical lattice clock demonstrator is being developed with a goal instability of 1× 10−15τ−1/2 and a goal inaccuracy of 5×10−17. For the design of the clock, techniques and approaches suitable for later space application are used, such as modular design, diode lasers, low power consumption, and compact dimensions. The atomic part is operative at the point where atoms are reliably trapped into the optical lattice. The latest results and future perspectives will be presented.
