Mobile Optical Clock with Sr in a magic optical lattice

The advent of femtosecond comb systems as optical clockworks (Nobel prize 2005) has enabled optical frequencies to be used as a time standard. The higher frequencies of the transitions enable unprecedented accuracy which opens a whole new field of applications, from precision tests of fundamental physics to mineral exploration. This project aims at the realization of a mobile frequency standard, which would allow precision time comparison as well as relativistic geodesy with potential accuracies of only a few cm. This instrument could act as a prototype for future space missions aiming at fundamental tests or laser-ranging gravitational wave detection.
