N2 - We demonstrate theoretically control over the time-frequency mapping in two-color high-order harmonic generation. By changing the temporal delay between a driving field and its orthogonally polarized second harmonic we are able to preferentially select between the short- and long-orbit contributions to the harmonic emission along both polarization axes. This trajectory selection is interpreted through use of classical and quantum orbit models. We further observe, and explain, different modulations in intensity of odd and even order harmonic emission modeled via a full macroscopic propagation model coupled to a single-atom quantum orbit treatment.
