Dichroic Electron Emission Patterns from Oriented Helium Ions
Niclas Wieland, Klaus Bartschat, Filippa Dudda +17
We report a joint experimental and theoretical study using a combination of polarization-controlled free-electron-laser (FEL) and near-infra\-red (NIR) pulses in a synchronized two…
Circular Dichroism in Multiphoton Ionization of Resonantly Excited Helium Ions near Channel Closing
Rene Wagner, Markus Ilchen, Nicolas Douguet +16
The circular dichroism (CD) of photoelectrons generated by near-infrared (NIR) laser pulses using multiphoton ionization of excited He ions in the 3p(m=+1) state. The ions were…
Strong-Field Ionization Phenomena Revealed by Quantum Trajectories
Taylor Moon, Klaus Bartschat, Nicolas Douguet
We investigate the photoionization dynamics of atoms subjected to intense, ultrashort laser pulses through the use of quantum trajectories. This method provides a unique and consis…
Opportunities for Gas-Phase Science at Short-Wavelength Free-Electron Lasers with Undulator-Based Polarization Control
Markus Ilchen, Enrico Allaria, Primož Rebernik Ribič +44
Free-electron lasers (FELs) are the world's most brilliant light sources with rapidly evolving technological capabilities in terms of ultrabright and ultrashort pulses over a large…
High-Order Harmonic Generation in Helium: A Comparison Study
A. T. Bondy, S. Saha, J. C. del Valle +4
We report a detailed study of high-order harmonic generation (HHG) in helium. When comparing predictions from a single-active-electron model with those from all-electron simulation…
