Results for the energy spectra of the electrons scattered on a potential in the presence of a bichromatic field of frequencies ω and 2ω are obtained based on 1D numerical integration of the time dependent Schrödinger equation. Both the perturbative and the nonperturbative regimes are investigated for low scattering energies and a laser frequency that is close to that of CO2 lasers. Special attention is paid to the influence of the relative phase between the harmonic and the laser field on the features of the laser-assisted signals.
