Ultrafast light-induced dynamics in the microsolvated biomolecular indole chromophore with water

open access: yesNature Communications, 2022
Experimentally following the ultrafast dynamics of microsolvated molecules is challenging due to the inherently produced soup mix of various gas-phase aggregates.

An Optimized Approach for Serial Crystallography Using Chips

open access: yesCrystals, 2023
Serial crystallography is a rapidly developing method for the determination of the structure of biomolecules at room temperature at near-atomic resolution from an ensemble of small crystals. Numerous advances in detectors, data analysis pipelines, sample

Minimizing attosecond CEP jitter by carrier envelope phase tuning [PDF]

open access: yesEPJ Web of Conferences, 2019
Minimizing the CEP jitter of isolated attosecond pulses (IAP) will be important for future applications. This jitter is experimentally and theoretically investigated and can be minimized when the driving pulse is near its Fourier limit but with slightly ...

Roles of Free Electrons and H2O2 in the Optical Breakdown-Induced Photochemical Reduction of Aqueous [AuCl4]- [PDF]

open access: yes, 2017
Free electrons and H2O2 formed in an optical breakdown plasma are found to directly control the kinetics of [AuCl4]− reduction to form Au nanoparticles (AuNPs) during femtosecond laser-assisted synthesis of AuNPs.

Analogy between free electron laser and channeling by crystal planes

open access: yes, 2004
The trapping of electrons in the ponderomotive potential wells, which governs a free electron laser or inverse free electron laser at high gain, is analogous to the channeling of charged particles by atomic planes of a crystal.

Operational experience with Adaptive Gain Integrating Pixel Detectors at European XFEL

open access: yesFrontiers in Physics
The European X-ray Free Electron Laser (European XFEL) is a cutting-edge user facility that generates per second up to 27,000 ultra-short, spatially coherent X-ray pulses within an energy range of 0.26 to more than 20 keV.

Chaos in free electron laser oscillators

open access: yes, 2009
The chaotic nature of a storage-ring Free Electron Laser (FEL) is investigated. The derivation of a low embedding dimension for the dynamics allows the low-dimensionality of this complex system to be observed, whereas its unpredictability is demonstrated,

Quantum theory of SASE FEL [PDF]

open access: yes, 2005
We describe a free-electron laser (FEL) in the Self-Amplified Spontaneous Emission (SASE) regime quantizing the electron motion and taking into account propagation effects. We demonstrate quantum purification of the SASE spectrum, i.e.
