    "abstract": "We report on experimental observation of electromagnetically induced\ntransparency and slow-light (vg ~ c/607) in atomic sodium vapor, as a potential\nmedium for a recently proposed experiment on slow-light enhanced relative\nrotation sensing [11]. We have performed an interferometric measurement of the\nindex variation associated with a two-photon resonance to estimate the\ndispersion characteristics of the medium that is relevant to the slow-light\nbased rotation sensing scheme. We also show that the presence of\ncounter-propagating pump beams in an optical Sagnac loop produces a backward\noptical phase conjugation beam that can generate spurious signals, which may\ncomplicate the measurement of small rotations in the slow-light enhanced\ngyroscope. We identify techniques for overcoming this constraint.",
