By performing a joint theoretical and experimental investigation on the high-order above-threshold ionization spectrum, the dominant role of the third-return-recollision trajectories in the region near the cutoff due to the ionic Coulomb field is identified. This invalidates the key assumption adopted in the conventional laser-induced electron-diffraction (LIED) approach that the first-return-recollision trajectories dominate the spectrum according to strong-field approximation. Our results…

Recollision of excited electron in below-threshold nonsequential double ionization

Recollision is the most important post-tunneling process in strong-field physics, but so far has been restricted to interaction between the first ionized electron and the residual ion in

Controlling electron recollision with combined linear and circular polarization

We theoretically investigate the non-sequential double ionization of Ar atoms in the combined fields of linearly polarized laser and circularly polarized laser through 3D semiclassical simulations.

Molecular potential anisotropy probed by electron rescattering in strong-field ionization of molecules

One of the main differences between rescattering following laser-induced ionization of atoms and molecules and electron-ion collisions performed with electron beams is the quivering dynamics of the

The LIID scheme may be extended to molecular systems and provides a promising approach for imaging of the gas-phase molecular dynamics induced by a strong laser field with unprecedented spatial and temporal resolution.

We review the phenonomena which occur in multiphoton physics when the electric field of the applied laser radiation becomes comparable with the Coulomb field strength seen by an electron in the

During strong-field multiphoton ionization, a wave packet is formed each time the laser field passes its maximum value, and one important parameter which determines the strength of these effects is the rate at which the wave packet spreads in the direction perpendicular to the laser electric field.

Trajectory-resolved Coulomb focusing in tunnel ionization of atoms with intense, elliptically polarized laser pulses.

By performing a complete mapping of the three-dimensional electron momentum, this Letter finds a surprisingly sensitive dependence of Coulomb focusing on the initial transverse momentum distribution, i.e., the momentum at the moment of birth of the photoelectron.

Imaging ultrafast molecular dynamics with laser-induced electron diffraction

The method has the sensitivity to measure a 0.1 Å displacement in the oxygen bond length occurring in a time interval of ∼5 fs, which establishes LIED as a promising approach for the imaging of gas-phase molecules with unprecedented spatio-temporal resolution.

Experimental advances with laser intensities above1 TW/cm(2), with pulse durations between roughly 50 and 5 fs, have led to the discovery of new atomic effects that include examples of startlingly

Spectral focusing of the recolliding electron in high-order harmonic generation driven by two-color fields is shown to be a powerful tool for isolating and enhancing hidden spectral features of the

Experimental and theoretical investigations of the wavelength dependence of the nonsequential double ionization (NSDI) process of the xenon atom in intense laser fields are reported. The observed

Sub-laser-cycle electron pulses for probing molecular dynamics

This work proposes that the electrons themselves can be exploited for ultrafast measurements, and uses a ‘molecular clock’, based on a vibrational wave packet in H2+, to show that distinct bunches of electrons appear during electron–ion collisions with high current densities, and durations of about 1 femtosecond (10-15 s).
