Phys. Rev. Lett. 67, 181–184 (1991)Atomic interferometry using stimulated Raman transitionsReceived 23 April 1991; published in the issue dated 8 July 1991 The mechanical effects of stimulated Raman transitions on atoms have been used to demonstrate a matter-wave interferometer with laser-cooled sodium atoms. Interference has been observed for wave packets that have been separated by as much as 2.4 mm. Using the interferometer as an inertial sensor, the acceleration of a sodium atom due to gravity has been measured with a resolution of 3×10-6 after 1000 sec of integration time. © 1991 The American Physical Society URL:
