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…
Time-domain Brillouin scattering assisted by diffraction gratings
Osamu Matsuda, Thomas Pezeril, Ievgeniia Chaban +2
Absorption of ultrashort laser pulses in a metallic grating deposited on a transparent sample launches coherent compression/dilatation acoustic pulses in directions of different or…
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…
