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…
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…
Time-domain Brillouin scattering for the determination of laser-induced temperature gradients in liquids
I. Chaban, D. Shin, C. Klieber +4
We present an optical technique based on ultrafast photoacoustics to precisely determine the local temperature distribution profile in liquid samples in contact with a laser heated…
Ultrafast non-thermal laser excitation of gigahertz longitudinal and shear acoustic waves in spin-crossover molecular crystals []
T. Parpiiev, M. Servol, M. Lorenc +6
We report GHz longitudinal as well as shear acoustic phonons photoexcitation and photodetection using femtosecond laser pulses in a spin-crossover molecular crystal. From our exper…
Ultrafast electron-phonon-magnon interactions at noble metal-ferromagnet interfaces
V. Shalagatskyi, O. Kovalenko, V. Shumylo +8
Ultrafast optical excitation of gold-cobalt bilayers triggers the nontrivial interplay between the electronic, acoustic, and magnetic degrees of freedom. Laser-heated electrons gen…
Nonlinear Acoustics at GHz Frequencies in a Viscoelastic Fragile Glass Former
Christoph Klieber, Vitalyi E. Gusev, Thomas Pezeril +1
Using a picosecond pump-probe ultrasonic technique, we study the propagation of high-amplitude, laser-generated longitudinal coherent acoustic pulses in the viscoelastic fragile gl…
Magnetization switching by ultrashort acoustic pulses
O. Kovalenko, T. Pezeril, V. V. Temnov
It is shown theoretically that a single a few picoseconds long acoustic pulse can reverse magnetization in a magneto-strictive material Terfenol-D. Following giant magneto-elastic…
Direct Visualization of Laser-Driven Focusing Shock Waves
Thomas Pezeril, Gagan Saini, David Veysset +4
Cylindrically or spherically focusing shock waves have been of keen interest for the past several decades. In addition to fundamental study of materials under extreme conditions, c…
