Dual-beam multipass cell compression for time-resolved femtosecond spectroscopy setups [PDF]

EPJ Web of Conferences
We present a dual-beam single multi-pass cell compressor designed for applications in time-resolved pump-probe spectroscopy. A single MPC simultaneously compresses two beams with different pulse energies to the same pulse duration, allowing for ...

Ultrafast Coherent Spectroscopy [PDF]

, 1988
Coherent spectroscopy, initially started in the mid-sixties, is intimately conncected with the development of intense coherent light sources. The generation of ultrashort light pulses enabled coherent spectroscopy to be extended to real-time measurements of rapid dynamic processes on the time scale of 10−12 s.

Ultrafast graphene photodetector [PDF]

Nature Nanotechnology, 2009
The electronic properties of graphene are unique and are attracting increased attention to this novel 2-dimensional system. Its photonic properties are not less impressive. For example, this single atomic layer absorbs through direct interband transitions a considerable fraction of the light (~2.3%) over a very a broad wavelength range.

Energy Scaling of Infrared Femtosecond Pulses by Dual-Chirped Optical Parametric Amplification

IEEE Photonics Journal, 2017
We present an energy-scaling experiment on a femtosecond infrared pulse using dual-chirped optical parametric amplification (DC-OPA). A total output energy exceeding 100 mJ with 36-fs pulse duration was achieved in the infrared region, which is ...

Toward Full Interoperability in Materials Science: Integrating Workflows With Knowledge Graphs

Advanced Engineering Materials, EarlyView.
The connection of conceptual workflow design, portable execution, and ontology‐based semantics leading to provenance‐rich knowledge graphs are main contributors to interoperability in materials science and a prerequisite to AI‐assisted orchestration and for interoperable Materials Acceleration Platforms.

Compact laser-driven plasma X-ray source for time-resolved diffraction, spectroscopy and imaging experiments at ELI Beamlines

Journal of Synchrotron Radiation
In this work, experimentally measured characteristics of a kilohertz laser-driven Cu plasma X-ray source that was recently commissioned at the ELI Beamlines facility are reported. The source can be driven either by an in-house developed high-contrast sub-

Toward time-resolved laser T-jump/X-ray probe spectroscopy in aqueous solutions

Structural Dynamics, 2019
Most chemical and biochemical reactions in nature and in industrial processes are driven by thermal effects that bring the reactants above the energy barrier for reaction.

Ultrafast Dynamics of Metallo-Dielectric Core-Shell Particles [PDF]

, 2008
Optical properties of metallic nano-structures have attracted a lot of attention in the past decades. In this thesis, we focus on nano-sized silica-core gold-shell particles, study the linear, nonlinear and acoustic vibrations of the particles.

FastNano Liquid: An Automated Platform for Small‐Angle X‐ray Scattering‐Based Materials Discovery

Advanced Engineering Materials, EarlyView.
We present FastNano Liquid, an automated small‐ and wide‐angle X‐ray scattering platform for the combined synthesis and characterization of (nano)materials. The platform is coupled to varied reactor workflows for both in situ studies of reaction kinetics and ex situ screening of synthesis conditions to support machine learning‐guided exploration ...

The Rise of Ultrafast Waves [PDF]

Developmental Cell, 2018
Traditionally, biochemical traveling waves are thought to propagate due to a coupling of bistable reactions with diffusion. Recent work proposes mechanisms by which cells achieve fast signaling without necessarily resorting to pure bistability or diffusion-mediated coupling.
