The authors present a general nonperturbative approach for the study of multiple high-order harmonic generation (HHG) in intense one- and two-color laser fields. The procedure consists of the following elements: (1) Determination of the complex quasienergy states by means of the generalized Floquet formalism, wherein the Floquet Hamiltonian is discretized by the complex-scaling generalized pseudospectral technique. (2) Calculation of the HHG spectra within the dipole and acceleration frameworks. The method is applied to the study of the two-color phase control of HHG processes of atomic hydrogen with the fundamental frequencies 532 and 775 nm and their third harmonics. Detailed results will be presented.
