Hydrogen atom interacting with a multifrequency laser field: ionization and harmonic generation.
The response of a hydrogen atom submitted to a multiharmonic laser field is studied. The relative phases of the harmonic components are critical both for atomic ionization and high-order harmonic generation. In the phase-locked case under adequate interference conditions, the inhibition of ionization is followed by an increase of the intensities of the generated harmonics.
