Megabar Shocks on a Benchtop
Yun Kai, Min Kim, Senpeng Lin +9
Techniques to generate megabar (100 GPa) pressure are critical for the study of materials under extreme conditions. However, kJ-class lasers are typically needed to generate such e…
High-power laser beam shaping using a metasurface for shock excitation and focusing at the microscale
Yun Kai, Jet Lem, Marcus Ossiander +6
Achieving high repeatability and efficiency in laser-induced strong shock wave excitation remains a significant technical challenge, as evidenced by the extensive efforts undertake…
Additive Laser Excitation of Giant Nonlinear Surface Acoustic Wave Pulses
Jude Deschamps, Yun Kai, Jet Lem +6
The laser ultrasonics technique perfectly fits the needs for non-contact, non-invasive, non-destructive mechanical probing of samples of mm to nm sizes. This technique is however l…
Soft x-rays induce femtosecond solid-to-solid phase transition
Franz Tavella, Hauke Höppner, Victor Tkachenko +12
Soft x-rays were applied to induce graphitization of diamond through a non-thermal solid-to-solid phase transition. This process was observed within poly-crystalline diamond with a…
