Abstract
Two-component pump of atoms with strong low-frequency field and ultrashort pulse of high-frequency radiation is proposed for high-order harmonic generation (HHG). At specific relative phase between pump fields HHG will occur with a selection of narrow frequency domain that is important for applications. In addition, the total number of photoelectrons can be essentially less in this case compare to traditional HHG scheme that improves phase-matching condition. Interaction of atoms with such two-component field can also restrict HHG efficiency owing to harmonic absorption while the atom tunnel ionization. Reversing this effect is proposed for harmonic amplification with additional high-frequency pump radiation.
