FID signal of atomic |Δm| = 2 coherence created by a linearly-polarized pump pulse propagating along the probe beam: (a) time dependence of the rotation signal \(\theta (t)\) in magnetic field B z = 95 mG, under continuous probing. (b) FID signal of atomic coherence \(\theta ({B}_{z},\,t)\) as a function of time and B z . (c) The amplitude and decay time of the coherence FID signals dependence on the probe detuning. (d) Decay rates of atomic polarization and coherence on the probe light intensity (CW probing with light detuned by 24 MHz to the blue). Error bars like in Fig. 3.
