(color online) (a)–(d) The correlated electron momentum distributions along the x direction and (e)–(h) the ion momentum distributions of Ar in two-color elliptically polarized laser pulses for different ellipticities (ε₂ = 0.0, 0.4, 0.8, 1.0). The laser intensity is 0.2 PW/cm², the electric field amplitude ratio γ_E = 1.4, the fundamental frequency ω_r = 0.0576 a.u. (790 nm in wavelength), and the second harmonic frequency ω_b = 0.115 a.u. (395 nm in wavelength).
