| 摘 要： | We investigate the ionization and high-order harmonic generation of a hydrogen atom in high-frequency (several atomic units) super strong (up to several tens of atomic units) dichromatic laser fields.An effective iterative method in the framework of high-frequency Floquet theory is used in the calculations.We have considered two kinds of dichromatic laser field,i.e.1ω-2ω and 1ω-3ω.We find that,in both the cases,the ionization and high-order harmonic generation show evident dependence on the relative phase and strength of the additional harmonic field.The dynamical origin of these interference effects is also discussed.
