The generation of harmonics from two mixed laser fields of noncommensurate frequencies is analyzed. We address the case of the hydrogen atom irradiated both by a laser field of wavelength λ0=1231 nm with an intensity I0=4×1013 W cm-2 and by a tunable laser field of wavelength approximately λ1=2071 nm with an intensity I1I0. We study the temporal profile and the efficiency of two-color harmonic generation far from the saturation regime. We focus on situations in which an even number of photons ω0 are absorbed in association with the emission or absorption of one photon ω1 of the second laser. The influence of the second laser on the production of the main harmonic spectrum is also analyzed.
