【 摘 要 】

Atomic interferometry is a very sensitive technique to measure small forces. Here we present an overview of the progress towards interferometric measurements in our laboratory. We characterize the magnetic field noise and describe the strategies to minimize the sensitivity to magnetic field fluctuations. We introduce as well a system for Raman excitation with minimum phase noise and the frequency filtering needed to implement it. Finally, we demonstrate atomic interferometry with a frequency sensitivity of 3 Hz.
