The new generation of atomic clocks, using cold atoms, require laser beams with high spectral quality and very fine frequency control.

In this article, the interest of space environment for cold atoms is outlined. After a brief review of cooling techniques and Bose–Einstein condensation, the case of atomic clocks in microgravity is discussed. The scientific objectives of the Europ

Le but de cet article est de presenter le nouveau gyrometre a atomes que nous concevons au laboratoire. L'extreme sensibilite des capteurs inertiels a atomes n'est plus a demontrer, mais ce type de dispositif est souvent complexe et tres encombrant.

Imperfect atomic state preparation in an optically pumped beam resonator results in over-Poissonian fluctuations of the fluorescence emission of residual unpumped atoms. This excess noise is induced by the frequency noise of the pump laser. We evalua

We describe the operation of a cold atom clock in reduced gravity. We have recorded the cesium hyperfine resonance signal at a frequency near 9.2 GHz in the \(\) gravity environment produced by jet plane parabolic flights. With a resonance width of 7
