摘要

Using the one-dimensional ion mode, we theoretically investigate the dynamics ionization process and the highorder harmonic generation of the He+ subject to different kinds of two-colour laser pulses with the same fundamental frequency but various harmonic frequencies. It is found that from the results calculated by numerically solving the time-dependent Schrodinger equation, the two-colour laser pulse with the fundamental and harmonic frequencies enables the power spectrum of high-order harmonic generation to increase by a few orders of magnitude and the yield of He2+ to enhance significantly when the harmonic frequency of the laser pulse is close to the energy interval between the ground state and the first excited state of He+; even the harmonic field added into the pulse is much weaker than the fundamental one.
