Abstract:We present numerical simulations of ultrafast multiphoton ionization dynamics in a twodimensional atomic model driven by co-and counterrotating circularly polarized single-color and bichromatic carrier envelope phase (CEP) stable ultrashort laser pulse sequences. Taking into account phase variations due to CEP fluctuations and the Gouy phase, our results accurately reproduce recently measured photoelectron momentum distributions [1][2][3][4]. The time evolution of the complexvalued electron wave function in co… Show more
