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…
Nonlinear optical absorption in nanoscale films revealed through ultrafast acoustics
Ievgeniia Chaban, Radoslaw Deska, Gael Privault +7
Herein we describe a novel spinning pump-probe photoacoustic technique developed to study nonlinear absorption in thin films. As a test case, an organic polycrystalline thin film o…
Direct Observation of Coherent Longitudinal and Shear Acoustic Phonons in TaAs Using Ultrafast X-ray Diffraction
Min-Cheol Lee, N. Sirica, S. W. Teitelbaum +18
Using femtosecond time-resolved X-ray diffraction, we investigated optically excited coherent acoustic phonons in the Weyl semimetal TaAs. The low symmetry of the (112) surface pro…
Tracking picosecond strain pulses in heterostructures that exhibit giant magnetostriction
S. P. Zeuschner T. Parpiiev, T. Pezeril, A. Hillion +8
We combine ultrafast X-ray diffraction (UXRD) and time-resolved Magneto-Optical Kerr Effect (MOKE) measurements to monitor the strain pulses in laser-excited TbFe2/Nb heterostructu…
Ultrafast tunable modulation of light polarization at terahertz frequencies
Vincent Juvé, Gwenaëlle Vaudel, Zoltan Ollmann +4
Controlling light polarization is one of the most essential routines in modern optical technology. Since the demonstration of optical pulse shaping by spatial light modulators and…
