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 π and 2π pulses, respectively. In a crystal of (Formula presented) doped (Formula presented) we experimentally observe spin echo efficiency as high as 46% of the free induction decay signal.
