Gyromètre à atomes froids : Etude de la stabilité limite et des effets systématiques liés aux séparatrices lasers.

Abstract : This thesis present the study of a cold atoms gyroscope based on atom interferometry. The interferometer used cold cesium atoms which are manipulated with stimulated Raman transitions. The improvement of the experimental setup have allowed to reach a sensitivity similar to the best optical fiber gyroscope. Especially, we characterized the performances bring about a new Raman laser desing and the atom detection system. In addition, we have studied spurious phase shifts induced by the Raman interactions and have shown they are the main limitation for the long term stability and the accuracy.
