Photoelectron momentum distributions of the model atom in counter-rotating polarization case at different ellipticities: [(a)–(d)] ε = 0.75 and [(e)–(h)] ε = 0.25 with time delays: (a) and (e) ωt_d = 0.5 σ, (b) and (f) ωt_d = σ, ωt_d = 1.5π, and (d) and (h) ωt_d = 2σ. (i) and (j) Theoretical results of parameter | A_γ|² at elliptivities: ε = 0.75 and ε = 0.25, respectively. Other laser parameters are the same as those in Fig. 1.
