摘　　要：We investigate the elliptical high-order harmonic generation(HHG)from the ground state of H_(2)^(+)subjected to linearly polarized laser fields,by numerically solving the three-dimensional(3D)time-dependent Schrödinger equation(TDSE)and using the strong-field approximation(SFA)models.Highly elliptical HHG is yielded at intermedial alignment angles from the TDSE,while the standard SFA model fails to predict this.By including the coulomb potential and the stark shift corrections,we yield qualitative agreement results with the TDSE.The comparisons show that in the description of elliptical HHG,both the coulomb potential and the stark-shift are necessary.
