(a) The time-frequency image (background), and the superimposed classical recombination (circles) paths of electrons for ω 0 τ = −0.8 π . (b) Same as panel (a), but for the case of ω 0 τ = −0.2 π . In the calculation, other parameters are the same as those in Fig.  3 . The color bar is in logarithmic scale.
