I will present some recent results for strong-laser-field induced processes in complex laser fields. By complex fields I mean the fields which are different from a linearly polarized monochromatic periodic field. Examples are elliptically polarized field, bicircular field, orthogonally polarized two-color field (OTC), and few-cycle pulse . Polarization of high-order harmonics generated by atoms or molecules can be controlled using the OTC field [2-4]. Angle-resolved photoelectron spectra in above-threshold ionization by OTC field exhibit particular symmetries [1,5]. Theoretical methods used to consider these processes include improved strong-field approximation, quantum-orbit theory, and solutions of the time-dependent Schrödinger equation . Particular attention will be devoted to recently discovered trifurcation in phase-dependent asymmetry in high-order above-threshold ionization of cesium atoms by 3100 nm few-cycle laser pulses and explanations in terms of time-domain holography .
