(color online) The correlated electron momentum distributions along the x direction for Ar atoms at the recollision time in the two-color elliptically polarized laser pulses for different ellipticities (ε2 = 0.0, 0.4, 1.0). The laser parameters are the same as those in Fig. 2. The distributions correspond to the events with travelling time less than 0.5 o.c. (top row) and larger than 0.5 o.c. (bottom row).
