Phase delays in above-threshold ionization
S. D. López, S. Donsa, S. Nagele +2
Relative phases of atomic above-threshold ionization wavepackets have been investigated in a recent experiment [L. J. Zipp, A. Natan, and P. H. Bucksbaum, Optica \textbf{1}, 361-36…
Towards the complete phase profiling of attosecond wave packets
Jaco Fuchs, Nicolas Douguet, Stefan Donsa +5
Realistic attosecond wave packets have complex profiles that, in dispersive conditions, rapidly broaden or split into multiple components. Such behaviors are encoded in sharp featu…
Angle-resolved time delays for shake-up ionization of helium
Stefan Donsa, Manuel Ederer, Renate Pazourek +2
Recent angle-resolved RABBITT experiments have shown that the photoionization time delay depends on the emission angle of the photoelectron. In this work we demonstrate that for ph…
Theory of Subcycle Linear Momentum Transfer in Strong-Field Tunneling Ionization
Hongcheng Ni, Simon Brennecke, Xiang Gao +8
Interaction of a strong laser pulse with matter transfers not only energy but also linear momentum of the photons. Recent experimental advances have made it possible to detect the…
Time delays from one-photon transitions in the continuum
Jaco Fuchs, Nicolas Douguet, Stefan Donsa +5
Attosecond photoionisation time delays reveal information about the potential energy landscape an outgoing electron wavepacket probes upon ionisation. In this study we experimental…
Circular holographic ionization-phase meter
Stefan Donsa, Nicolas Douguet, Joachim Burgdörfer +2
We propose an attosecond XUV-pump IR-probe photoionization protocol that employs pairs of counter-rotating consecutive harmonics and angularly resolved photoelectron detection, the…
