The determination of photoemission time delays requires taking into account the measurement process, involving the interaction with a probing infrared field, and this contribution can be estimated using a universal formula and is found to account for a substantial fraction of the measured delay.
Attosecond imaging of molecular electronic wavepackets

- Physics, Chemistry
- 1 March 2010
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…

- 28 July 2009
We photoionize nitrogen molecules with a train of extreme ultraviolet attosecond pulses together with a weak infrared field. We measure the phase of the two-color two-photon ionization transition…
Two-colour IR+XUV spectroscopies: the “soft-photon approximation”
We address several questions related to the nonlinear ionization processes observed when atoms are in the simultaneous presence of intense and coherent infrared (IR) and extreme ultraviolet (XUV)…
Attosecond dynamics through a Fano resonance: Monitoring the birth of a photoelectron

- 11 November 2016
Using spectrally resolved electron interferometry, the amplitude and phase of a photoelectron wave packet created through a Fano autoionizing resonance in helium is measured, raising prospects for detailed investigations of ultrafast photoemission dynamics governed by electron correlation, as well as coherent control over structured electron wave packets.
Stark ionization in dc and ac fields: An L2 complex-coordinate approach
- A. Maquet, S. Chu, W. Reinhardt
- Physics
- 1 June 1983
A finite-dimensional-matrix technique valid for computation of complex eigenvalues and eigenfunctions useful for discussing time evolution in both dc and ac Stark fields is presented. The complex…
Single-shot characterization of independent femtosecond extreme ultraviolet free electron and infrared laser pulses
