Spatiotemporal shaping of high power laser pulses based on stimulated brillouin scattering
Frontiers in Physics, 2023 We proposed and numerically demonstrated the combination of temporal and spatial shaping of high power nanosecond laser pulses based on stimulated Brillouin scattering (SBS) in this paper.

Impact of the spatial laser distribution on photocathode gun operation
Physical Review Special Topics. Accelerators and Beams, 2012 It is widely believed that a drive laser with uniform temporal and spatial laser profiles is required to generate the lowest emittance beam at the photoinjector.

Raman‐based label‐free microscopic analysis of the pancreas in living zebrafish larvae
FEBS Open Bio, EarlyView.Forward stimulated Raman scattering (F‐SRS) and epi coherent anti‐Stokes Raman scattering (E‐CARS) allow label‐free discrimination of distinct subcellular structures in the pancreas of living zebrafish larvae. Given the straightforward applicability, we anticipate broad implementation of Raman microscopy in other organs and across various biomedical ...

FEBS Open Bio, EarlyView.Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

All-optical structuring of laser-driven proton beam profiles
Nature Communications, 2018 Shaping particle beams generated from laser-plasma accelerators is challenging. Here the authors demonstrate an all-optical method to structure the accelerated proton beam by modulating and imprinting the spatial laser profile onto the proton beam.

Laser Beam Profiling in the Production Process [PDF]
Laser Technik Journal, 2010 AbstractLaser material processing is increasingly becoming more accepted in modern production lines. A growing number of production steps previously carried out by mechanical methods are being replaced by laser beam processing. The use of such high power laser beams requires adequate beam measurement technology to ensure product quality and to minimize

FEBS Open Bio, EarlyView.Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Laguerre-Gaussian and beamlet array as second generation laser heater profiles
Physical Review Accelerators and Beams, 2018 The microbunching instability is known to be detrimental to x-ray free electron laser performance. At the Linear Coherent Light Source, the microbunching instability is suppressed with a laser heater, which increases the uncorrelated energy spread of e ...
