Enhanced harmonic generation and wave-mixing via two-color multiphoton excitation of atoms/molecules
We consider harmonics generation and wave-mixing by two-color multi photon resonant excitation of three-level atoms/molecules in strong laser fields. The coherent part of the spectra corresponding to multicolor harmonics generation is investigated. T
