Electronic Population Transfer via Impulsive Stimulated X-Ray Raman Scattering with Attosecond Soft-X-Ray Pulses

Christoph Bostedt, Xiang Li, Andre Al Haddad, Solène Oberli, Siqi Li

Free-electron lasers provide a source of x-ray pulses short enough and intense enough to drive nonlinearities in molecular systems. Impulsive interactions driven by these x-ray pulses provide a way to create and probe valence electron motions with high tem ...

The role of transient resonances for ultra-fast imaging of single sucrose nanoclusters

Christoph Bostedt, Andre Al Haddad

Intense x-ray free-electron laser (XFEL) pulses hold great promise for imaging function in nanoscale and biological systems with atomic resolution. So far, however, the spatial resolution obtained from single shot experiments lags averaging static experime ...

Towards X-ray transient grating spectroscopy

Majed Chergui, Paul Beaud, Giulia Fulvia Mancini, Jérémy Raymond Jean Maurice Rouxel, Christian David

The extension of transient grating spectroscopy to the x-ray regime will create numerous opportunities, ranging from the study of thermal transport in the ballistic regime to charge, spin, and energy transfer processes with atomic spatial and femtosecond t ...

Ultrafast Structural Dynamics of Nanoparticles in Intense Laser Fields

Christoph Bostedt, Alessandro Colombo, Giorgio Rossi

Femtosecond laser pulses have opened new frontiers for the study of ultrafast phase transitions and nonequilibrium states of matter. In this Letter, we report on structural dynamics in atomic clusters pumped with intense near-infrared (NIR) pulses into a n ...

Clusters and Nanocrystals

Christoph Bostedt, Daniela Rupp

Clusters and nanocrystals constitute intermediates between molecules and condensed matter. Due to their finite size, clusters have a wide spectrum of applications ranging from building blocks for novel materials to model systems for fundamental investigati ...

Nanosecond electron pulses in the analytical electron microscopy of a fast irreversible chemical reaction

We show how the kinetics of a fast and irreversible chemical reaction in a nanocrystalline material at high temperature can be studied using nanosecond electron pulses in an electron microscope. Infrared laser pulses first heat a nanocrystalline oxide laye ...

Perspective: Opportunities for ultrafast science at SwissFEL

Majed Chergui, Paul Beaud

We present the main specifications of the newly constructed Swiss Free Electron Laser, SwissFEL, and explore its potential impact on ultrafast science. In light of recent achievements at current X-ray free electron lasers, we discuss the potential territor ...

Free-electron-laser coherent diffraction images of individual drug-carrying liposome particles in solution

Giorgio Margaritondo, Ying Chen, Ke Peng

Using the excellent performances of a SACLA (RIKEN/HARIMA, Japan) X-ray free electron laser (X-FEL), coherent diffraction imaging (CDI) was used to detect individual liposome particles in water, with or without inserted doxorubicin nanorods. This was possi ...

Generation and measurement of sub-micrometer relativistic electron beams

Rasmus Ischebeck, Eugenio Ferrari, Christian David

The generation of low-emittance electron beams has received significant interest in recent years. Driven by the requirements of X-ray-free electron lasers, the emittance of photocathode injectors has been reduced significantly, with corresponding increase ...
