Laser-Induced Electron Fresnel Diffraction in Tunneling and Over-Barrier Ionization
文献摘要：
Photoelectron momentum distribution in strong-field ionization has a variety of structures that reveal the com-plicated dynamics of this process.Recently,we identified a low-energy interference structure in the case of a super-intense extreme ultraviolet(XUV)laser pulse and attributed it to the laser-induced electron Fresnel diffraction.This structure is determined by the laser-induced electron displacement[Geng et al.Phys.Rev.A 104(2021)L021102].In the present work,we find that the Fresnel diffraction picture also appears in the tun-neling and over-barrier regime of ionization by short pulses.However,the electron displacement is now induced by the electric field component of the laser pulse rather than the magnetic field component in the case of the super-intense XUV pulse.After corresponding modifications to our quantum and semiclassical models,we find that the same physical mechanism of the Fresnel diffraction governs the low-energy interference structures along the laser polarization.The results predicted by the two models agree well with the accurate results from the numerical solution to the time-dependent Schr?dinger equation.
