Generation of strong-field spectrally tunable terahertz pulses
The ideal laser source for nonlinear terahertz spectroscopy offers large versatility delivering both ultra-intense broadband single-cycle pulses and user-selectable multi-cycle pulses at narrow linewidths. Here we show a highly versatile terahertz laser pl ...
OPTICAL SOC AMER2020A compact and cost-effective hard X-ray free-electron laser driven by a high-brightness and low-energy electron beam
Majed Chergui, Leonid Rivkin, Rasmus Ischebeck, Mike Seidel, Paolo Craievich, Christoph Peter Hauri, Paul Beaud, Christopher Alexander Arrell, Giulia Fulvia Mancini, Camila Bacellar Cases Da Silveira, Eugenio Ferrari, Thomas Schmidt, Thomas Schietinger, Sven Reiche, Lukas Stingelin
We present the first lasing results of SwissFEL, a hard X-ray free-electron laser (FEL) that recently came into operation at the Paul Scherrer Institute in Switzerland. SwissFEL is a very stable, compact and cost-effective X-ray FEL facility driven by a lo ...
NATURE RESEARCH2020Experimental station Bernina at SwissFEL: condensed matter physics on femtosecond time scales investigated by X-ray diffraction and spectroscopic methods
Christoph Peter Hauri, Paul Beaud, Christopher Alexander Arrell, Giulia Fulvia Mancini, Jochen Rittmann
The Bernina instrument at the SwissFEL Aramis hard X-ray free-electron laser is designed for studying ultrafast phenomena in condensed matter and material science. Ultrashort pulses from an optical laser system covering a large wavelength range can be used ...
International Union of Crystallography (IUCr)2019SwissFEL: The Swiss X-ray Free Electron Laser
Leonid Rivkin, Rasmus Ischebeck, Paolo Craievich, Christoph Peter Hauri, Paul Beaud, Jochen Rittmann, Ishkhan Gorgisyan, Thomas Schmidt, Thomas Schietinger, Sven Reiche, Babak Kalantari, Lukas Stingelin
The SwissFEL X-ray Free Electron Laser (XFEL) facility started construction at the Paul Scherrer Institute (Villigen, Switzerland) in 2013 and will be ready to accept its first users in 2018 on the Aramis hard X-ray branch. In the following sections we wil ...
Mdpi Ag2017Subcycle Extreme Nonlinearities in GaP Induced by an Ultrastrong Terahertz Field
Christoph Peter Hauri, Mostafa Shalaby
We report on the experimental observation of extreme laser spectral broadening and a change in optical transmission in gallium phosphite induced by 25 MV/cm terahertz (THz) single-cycle internal field. Such intense THz radiation leads to twofold transient ...
American Physical Society2017THz streak camera method for synchronous arrival time measurement of two-color hard X-ray FEL pulses
Leonid Rivkin, Rasmus Ischebeck, Christoph Peter Hauri, Ishkhan Gorgisyan
The two-color operation of free electron laser (FEL) facilities allows the delivery of two FEL pulses with different energies, which opens new possibilities for user experiments. Measuring the arrival time of both FEL pulses relative to the external experi ...
Optical Society of America2017Fourier transform spectroscopy in the vibrational fingerprint region with a birefringent interferometer
We introduce a birefringent interferometer for Fourier transform (FT) spectroscopy in the mid-infrared, covering the vibrational fingerprint region (5-10 µm, 1000-2000 cm-1), which is crucial for molecular identification. Our interferometer empl ...
Optical Society of America2017Comparison of Thermal Detector Arrays for Off-Axis THz Holography and Real-Time THz Imaging
Christoph Peter Hauri, Mostafa Shalaby
In terahertz (THz) materials science, imaging by scanning prevails when low power THz sources are used. However, the application of array detectors operating with high power THz sources is increasingly reported. We compare the imaging properties of four di ...
2016Intense THz source based on BNA organic crystal pumped at Ti:sapphire wavelength
Christoph Peter Hauri, Mostafa Shalaby
We report on high-energy terahertz pulses by optical rectification (OR) in the organic crystal N-benzyl-2-methyl-4-nitroaniline (BNA) directly pumped by a conventional Ti:sapphire amplifier. The simple scheme provides an optical-to-terahertz conversion eff ...
