    "abstract": "The decoherence times of orthogonally phased components of the optical\ntransition dipole moment in a two-level system have been observed to differ by\nan order of magnitude. This phase anisotropy is observed in coherent transient\nexperiments where an optical driving field is present during extended periods\nof decoherence. The decoherence time of the component of the dipole moment in\nphase with the driving field is extended compared to T_2, obtained from\ntwo-pulse photon echoes, in analogy with the spin locking technique of NMR.",
