Frontiers of atomic high-harmonic generation
Markus C. Kohler, Thomas Pfeifer, Karen Z. Hatsagortsyan +1
In the past two decades high-harmonic generation (HHG) has become a key process in ultra-fast science due to the extremely short time-structure of the underlying electron dynamics…
Macroscopic aspects of relativistic x-ray assisted high-order harmonic generation
Markus C. Kohler, Karen Z. Hatsagortsyan
A theoretical model is developed describing high-order harmonic generation (HHG) from a gas of multiply-charged ions driven by a laser field of relativistic intensity. Macroscopic…
Electron correlation and interference effects in strong-field processes
Markus C. Kohler, Carsten Müller, Christian Buth +5
Several correlation and interference effects in strong-field physics are investigated. We show that the interference of continuum wave packets can be the dominant mechanism of high…
A novel vacuum ultra violet lamp for metastable rare gas experiments
Heiner Daerr, Markus Kohler, Peter Sahling +5
We report on a new design of a vacuum ultra violet (VUV) lamp for direct optical excitation of high laying atomic states e.g. for excitation of metastable rare gas atoms. The lamp…
Attochirp-free High-order Harmonic Generation
Markus C. Kohler, Christoph H. Keitel, Karen Z. Hatsagortsyan
A method is proposed for arbitrarily engineering the high-order harmonic generation phase achieved by shaping a laser pulse and employing xuv light or x rays for ionization. This r…
High-order harmonic generation enhanced by XUV light
Christian Buth, Markus C. Kohler, Joachim Ullrich +1
The combination of high-order harmonic generation (HHG) with resonant XUV excitation of a core electron into the transient valence vacancy that is created in the course of the HHG…
