Simulation of FEL pulse length calculation with THz streaking method

Ishkhan Gorgisyan

Having accurate and comprehensive photon diagnostics for the X-ray pulses delivered by free-electron laser (FEL) facilities is of utmost importance. Along with various parameters of the photon beam (such as photon energy, beam intensity, etc.), the pulse l ...

Femtosecond resolution timing jitter correction on a TW scale Ti:sapphire laser system for FEL pump-probe experiments

Christoph Peter Hauri

Intense ultrashort pulse lasers are used for fs resolution pumpprobe experiments more and more at large scale facilities, such as free electron lasers (FEL). Measurement of the arrival time of the laser pulses and stabilization to the machine or other sub- ...

Temporal broadening of attosecond photoelectron wavepackets from solid surfaces

Christopher Alexander Arrell

The response of solids to electromagnetic fields is of crucial importance in many areas of science and technology. Many fundamental questions remain to be answered about the dynamics of the photoexcited electrons that underpin this response, which can evol ...

Delivery of ultrashort spatially focused pulses through a multimode fiber for two photon endoscopic imaging

Demetri Psaltis, Christophe Moser, Salma Farahi, Edgar Emilio Morales Delgado

Due to their high number of supported modes, multimode optical fibers carry large amount of spatio-temporal information. However, propagation of a light pulse through a multimode optical fiber suffers from spatial distortions due to superposition of the va ...

Sub-femtosecond precision measurement of relative X-ray arrival time for free-electron lasers

Christoph Bostedt, Christoph Peter Hauri

Today's brightest coherent X-ray sources, X-ray free-electron lasers, produce ultrafast X-ray pulses for which full-width at half-maximum durations as short as 3 fs have been measured(1). There has been a marked increase in the popularity of such short pul ...

Direct observation of non-fully-symmetric coherent optical phonons by femtosecond x-ray diffraction

Paul Beaud

We directly measure by femtosecond time-resolved x-ray diffraction the E-g symmetry coherent phonon excited in bismuth by a strong optical pulse. The magnitude of the E-g mode observed is 0.2 pm peak-to-peak, compared against the 2.7-pm initial displacemen ...

Design and implementation of a flexible beamline for fs electron diffraction experiments

Fabrizio Carbone, Giulia Fulvia Mancini, Saverio Pagano

Ultrafast Electron Diffraction (UED) has been widely used to investigate the structural dynamics of molecules and materials. Femtosecond (fs) electron bunches are used to obtain diffraction images of a specimen upon photo-excitation by a temporally delayed ...
