Rev. Lett. 67, pp 34-37 (1991).http://hdl.handle.net/2003/2500410.17877/DE290R-3366We report on optically induced spin-echo phenomena associated with Zeeman coherences in a sublevel manifold. The experiments on the ground state of sodium show multiple echoes occurring periodically after a double-pulse excitation sequence in an inhomogeneous magnetic field. The echo formation mechanism is attributed to a light-shift-induced transfer of sublevel coherence among the nondegenerate substates. This mechanism is verified experimentally, using a modulated excitation scheme with subsequent phase-sensitive detection.enThe American Physical Society53010.1103/PhysRevLett.67.34article (journal)http://link.aps.org/abstract/PRL/v67/p34
