Abstract: The dependence of wavelength and intensity onatom frustrated double ionization (FDI) driven by linearly polarized laser field is studied using a three-dimensional classical ensemble model. The numerical results show that FDI prefers shorter wavelength and lower intensity. Moreover, the electron momentum distribution along the laser polarization direction from FDI shows a significant bimodal structure, which is well consistent with the recent experiment results. Inversion analysis of all FDI trajectories shows that FDI events are dominated by the ionization mechanism of the collision excitation field, which is consistent with low intensity of non-sequential double ionization. In addition, two pathways are significantly contributed to FDI. In one, the captured electron is immediately ionized after recollision, but is eventually captured by the Coulomb field. In other way, the captured electron first enters an excited state after recollision, then ionizes at the peak of the laser field, and finally is captured by the Coulomb field. For these two channeis, the longitudinal velocity and the corresponding vector potential of the captured electron are different at the ionization exit. Further studies demonstrate that the captured electron can be emitted to higher rydberg states at longer wavelengths and higher intensities of laser pulses.
