摘要：

We investigate the use of resonant optical Raman pulses to excite and rephase ground state spin coherences via the partial storage or shelving of atoms. Unlike direct-rf-excited spin echoes or off-resonant Raman echoes, the resonant Raman optical field efficiently excites and rephases the spin coherence using pi and 2 pi pulses, respectively. In a crystal of Pr3+ doped Y2SiO5, we experimentally observe spin echo efficiency as high as 46% of the free induction decay signal. [S0163-1829(98)50142-7].
