摘要：

We solve numerically the one-dimensional Schrodinger equation with a model potential for the case of excitation by two commensurate (the fundamental and third harmonic) intense laser fields and find a strong dependence of the atomic evolution and high-harmonic generation on the relative phase between the two fields. Our method employs the Kramers-Henneberger frame to exploit the insights pined from emphasizing the wave-packet dynamics of an electron oscillating under the influence of the strong laser fields.
