    "abstract": "We demonstrate the preparation and probing of the coherence between the\nhyperfine ground states |5S_{1/2}, F=1\u003e and |5S_{1/2}, F=2\u003e of the Rubidium 87\nisotope. The effect of various coherence control techniques, i.e. fractional\nStimulated Raman Adiabatic Passage and Coherent Population Return on the\ncoherence are investigated. These techniques are implemented using nearly\ndegenerate pump and Stokes lasers at 795nm (Rubidium D1 transition) which\ncouple the two hyperfine ground states via the excited state |5P_{1/2}, F=1\u003e\nthrough a resonant two-photon process, in which a coherent superposition of the\ntwo hyperfine ground states is established. The medium is probed by an\nadditional weak laser, which generates a four-wave mixing signal proportional\nto the ground state coherence, and allows us to monitor its evolution in time.\nThe experimental data are compared with numerical simulations.",
