摘　　要：We investigate the strong field ionization of argon using counter-rotating 2-color dual-elliptical phase-ofphase spectroscopy.We perform a multidimensional control experiment over the 2-color dual-elliptical laser field to modulate the photoelectron momentum spectra generated under strong fields.Incorporating the classical trajectory Monte Carlo calculation,we study the behavior of the relative phase contrast and the phase of phase and clarify how the enhancement of temporal precision in angular resolution measurements is achieved when the relative phase corresponds to the frequency of 3ω.Our results uncover the potential for using quantitatively controlled 2-color elliptical fields to realize precise probes of the attosecond ionization and scattering dynamics.
