A. 42, pp 1839-1841 (1990).http://hdl.handle.net/2003/2500210.17877/DE290R-2314We report on a spin-echo phenomenon that is induced between Zeeman sublevels by two laser pulses close to an optical resonance. The echo formation is due to a Zeeman light shift during the second off-resonant pulse; this light pulse creates a fictitious magnetic field that leads to the phase reversal of the spins. Our experimental results on the 2S1/2 sodium ground state are in good qualitative agreement with theoretical predictions.enThe American Physical Society53010.1103/PhysRevA.42.1839article (journal)http://link.aps.org/abstract/PRA/v42/p1839
