Fig. 3.10 Simulation of photoelectron distributions from coherent N 1 - versus N 2 -photon ionization
using ultrashort CRCP (red frames) or COCP (blue frames) bichromatic fields. To compare the
symmetry of the field and the electron distribution the polarization profile of one oscillation period
of the bichromatic field (blue curve) is superimposed. For clarity, the electric field is aligned to
match the photoelectron wave packets
