Abstract:Phase and time delays of atomic above-threshold ionization were recently experimentally explored in an ω − 2ω setting [Zipp et al, Optica 1, 361 (2014)]. The phases of wavepackets ejected from argon by a strong 2ω pulse were probed as a function of the relative phase of a weaker ω probe pulse. Numerical simulations solving the time-dependent Schrödinger equation (TDSE) displayed a sensitive dependence of the doubly differential momentum distribution on the relative phase between the ω and 2ω fields. Moreover, … Show more
