Laser-induced ultrafast structural transformations in thin Fe layer revealed by time-resolved X-ray diffraction
O. Liubchenko, J. Antonowicz, K. Sokolowski-Tinten +27
The ultrafast structural response of a thin iron film to sub-ps pulsed laser-induced heating has been investigated using time-resolved X-ray diffraction in the partial melting regi…
Orthogonal lattice distortions inside crystalline Si upon sub-threshold femtosecond laser-induced excitation
Angel Rodríguez-Fernández, Jan-Etienne Pudell, Roman Shayduk +18
Material processing with femtosecond lasers has attracted enormous attention because of its potential for technology and industrial applications. In parallel, time-resolved x-ray d…
Dynamics of Nanoscale Phase Decomposition in Laser Ablation
Yanwen Sun, Chaobo Chen, Thies J. Albert +19
Femtosecond laser ablation is a process that bears both fundamental physics interest and has wide industrial applications. For decades, the lack of probes on the relevant time and…
Directly observing atomic-scale relaxations of a glass forming liquid using femtosecond X-ray photon correlation spectroscopy
Tomoki Fujita, Yanwen Sun, Haoyuan Li +25
Glass forming liquids exhibit structural relaxation behaviors, reflecting underlying atomic rearrangements on a wide range of timescales. These behaviors play a crucial role in det…
