The decoherence times of orthogonally phased components of the opticaltransition dipole moment in a two-level system have been observed to differ byan order of magnitude. This phase anisotropy is observed in coherent transientexperiments where an optical driving field is present during extended periodsof decoherence. The decoherence time of the component of the dipole moment inphase with the driving field is extended compared to T_2, obtained fromtwo-pulse photon echoes, in analogy with the spin locking technique of NMR.Comment: 5 pages, 2 figures; replaced with published versio
