Abstract

We study high-order harmonics generated by an intense multicycle 800 nm laser pulse in the presence of a weaker 1300 nm mid-infrared (MIR) pulse. Additionally to the previously observed effects of yield enhancement, cutoff extension, and continuum generation, we report here a spectral shift of harmonic peaks controlled by the delay of the MIR pulse. We explain this effect considering the half-cycle to half-cycle behavior of the two-color field.
