We demonstrate a quantum stroboscope based on a sequence of identical attosecond pulses that are used to release electrons into a strong infrared (IR) laser field exactly once per laser cycle. The resulting electron momentum distributions are recorded as a function of time delay between the IR laser and the attosecond pulse train using a velocity map imaging spectrometer. Because our train of attosecond pulses creates a train of identical electron wave packets, a single ionization event can be…

Attosecond electron spectroscopy using a novel interferometric pump-probe technique.

An interferometric pump-probe technique that uses a free WP as a reference to measure a bound WP and analysis of the interferogram allows us to determine the bound WP components with a spectral resolution much better than the inverse of the AP duration.

Attosecond control of electron–ion recollision in high harmonic generation

We show that high harmonic generation driven by an intense near-infrared (IR) laser can be temporally controlled when an attosecond pulse train (APT) is used to ionize the generation medium, thereby

Attosecond control of electron emission from atoms

We demonstrate that the electron emission from atoms can be temporally controlled on an attosecond time scale. Electron wave-packets are formed by ionizing an atomic target with an attosecond pulse

Attosecond imaging of molecular electronic wavepackets

A strong laser field may tunnel ionize a molecule from several orbitals simultaneously, forming an attosecond electron–hole wavepacket. Both temporal and spatial information on this wavepacket can be

Intensity dependence of laser-assisted attosecond photoionization spectra

We study experimentally the influence of the intensity of the infrared (IR) probe field on attosecond pulse train (APT) phase measurements performed with the RABITT method (Reconstruction of

Macroscopic aspects of attosecond pulse generation

Attosecond pulses are generated by a macroscopic number of ionizing atoms interacting with a focused laser pulse, via the process of high harmonic generation. The physics of their generation consists

Low-energy photoelectron interference structure in attosecond streaking.

Numerically solving the time-dependent Schrödinger equation, it is shown that the phase of the electron wave-packets ionized by the linearly and circularly polarized attosecond pulses can be extracted from the interference structures of the direct and the near-forward rescattering electrons.

Attosecond Wave Packet Metrology

Attosecond pulses allow the study of electrons on their natural timescale. They are created from the interaction of atoms with ultrashort, intense laser pulses whose electric field approaches the

Electron choreography at the attosecond time scale

In this work, we report on coherent control of electron dynamics in atoms via attosecond pulse-shaping. We show that the photoelectron emission from argon gas produced by absorption of an attosecond

Time-Resolved Holography with Photoelectrons

Experiments in which metastable xenon atoms were ionized with intense 7-micrometer laser pulses from a free-electron laser recorded holographic structures that record underlying electron dynamics on a sublaser-cycle time scale, enabling photoelectron spectroscopy with a time resolution higher than the duration of the ionizing pulse.



Attosecond electron wave packet dynamics in strong laser fields.

A train of sub-200 attosecond extreme ultraviolet pulses with energies just above the ionization threshold in argon is used to create a train of temporally localized electron wave packets, resulting in dramatically enhanced above-threshold ionization in conditions where the IR field alone does not induce any significant ionization.

Direct XUV probing of attosecond electron recollision.

We demonstrate that the recolliding electron wave packet, fundamental to many strong field phenomena, can be directly imaged with sub-A spatial and attosecond temporal resolution using attosecond

Steering Attosecond Electron Wave Packets with Light

It is demonstrated that if the emitted electron wave packet is temporally confined to a small fraction of the oscillation period of the interacting light wave, its energy spectrum can be up- or downshifted by many times the laser photon energy without substantial broadening.

Controlling attosecond electron dynamics by phase-stabilized polarization gating

Attosecond electron wavepackets are produced when an intense laser field ionizes an atom or a molecule1. When the laser field drives the wavepackets back to the parent ion, they interfere with the

Theoretical description of atomic photoionization by an attosecond XUV pulse in a strong laser field: effects of rescattering and orbital polarization

A theoretical description of atomic photoionization by attosecond pulses in the presence of an intense laser pulse is presented. It is based on the numerical solving of the non-stationary Schrödinger

Amplitude and phase control of attosecond light pulses.

The generation, compression, and delivery on target of ultrashort extreme-ultraviolet light pulses using external amplitude and phase control is reported, demonstrating a practical method for synthesizing and controlling attosecond waveforms.

Isolated Single-Cycle Attosecond Pulses

The availability of single-cycle isolated attosecond pulses opens the way to a new regime in ultrafast physics, in which the strong-field electron dynamics in atoms and molecules is driven by the electric field of the attose Cond pulses rather than by their intensity profile.

Attosecond electron wave packet interferometry

Acomplete quantum-mechanical description of matter and its interaction with the environment requires detailed knowledge of a number of complex parameters. In particular, information about the phase

Observation of a Train of Attosecond Pulses from High Harmonic Generation

It is found that the harmonics are locked in phase and form a train of 250-attosecond pulses in the time domain, suggesting that Harmonic generation may be a promising source for attosecond time-resolved measurements.
