Abstract The thematic project addresses the construction of a sensor that can simultaneously be used as a standard for optical frequencies and gravimetry. Conventional standards consist in a laser oscillator locked to an ultra-stable optical cavity through a fast electronic servo using the Pound-Drever-Hall technique, which offers a good short-term stability. The accuracy and reproducibility of the device are obtained via spectroscopy of a very narrow resonance of an atomic cloud which, as a natural constant, is invariant in time. The concept of our standard is different, since the atoms are directly inserted in the cavity, thus taking advantage of the superradiant acceleration of the interaction of the light with the atoms. The post-doctor will work on the construction of this sensor. (AU) | |
