Femtosecond electron and X-ray source developments for time-resolved applications

This manuscript summarizes the different technological developments and scientific activities in the field of ultrafast laser and electron physics which I have carried out as part of my PhD thesis. The topics addressed in my thesis range from the developme ...

Towards enabling femtosecond helicity-dependent spectroscopy with high-harmonic sources

Christoph Peter Hauri, Fernando Ardana Lamas

Recent advances in high-harmonic generation gave rise to soft X-ray pulses with higher intensity, shorter duration and higher photon energy. One of the remaining shortages of this source is its restriction to linear polarization, since the yield of generat ...

Filling the Entire Terahertz Frequency Gap by Single-Cycle MV/Cm Pulses

Christoph Peter Hauri, Fernando Ardana Lamas

We demonstrate highly efficient Terahertz production and absolute phase control in the hardly accessible THz frequency gap (1-15 THz) by optical rectification in organic crystals leading to single-cycle field oscillations beyond 150MV/m and 0.5 Tesla. ...

Coherent Ultrafast Magnetization Dynamics Non-resonantly Induced in Cobalt by an Intense Terahertz Transient

Christoph Peter Hauri, Fernando Ardana Lamas

We demonstrate non-resonant magnetization dynamics in the ferromagnetic cobalt thin film induced by a record high-field Terahertz pulse. The magnetization dynamics are coherent and exactly follow the THz carrier oscillations. ...

A scheme for a shot-to-shot, femtosecond-resolved pulse length and arrival time measurement of free electron laser x-ray pulses that overcomes the time jitter problem between the FEL and the laser

Christoph Peter Hauri, Rasmus Ischebeck, Ishkhan Gorgisyan, Fernando Ardana Lamas

The recent entry of X-ray free electron lasers (FELs) to all fields of physics has created an enormous need, both from scientists and operators, for better characterization of the beam created by these facilities. Of particular interest is the measurement ...

Off-resonant magnetization dynamics phase-locked to an intense phase-stable terahertz transient

Christoph Peter Hauri, Fernando Ardana Lamas

Controlling magnetization dynamics with a femtosecond laser is attracting interest both in fundamental science and in industry because of the potential to achieve magnetic switching at ever faster speeds. Here, we report a coherent, phase-locked coupling b ...
