Picosecond ultrasonics with a free-running dual-comb laser
Justinas Pupeikis, Benjamin Willenberg, Francois Bruno +10
We present a free-running 80-MHz dual-comb polarization-multiplexed solid-state laser which delivers 1.8 W of average power with 110-fs pulse duration per comb. With a high-sensiti…
Cloaking, Trapping and Superlensing of Lamb Waves with Negative Refraction
François Legrand, Benoît Gérardin, François Bruno +4
We report on experimental and numerical implementations of devices based on the negative refraction of elastic guided waves, the so-called Lamb waves. Consisting in plates of varyi…
Laser beam shaping for enhanced Zero-Group Velocity Lamb modes generation
François Bruno, Jérôme Laurent, Paul Jehanno +2
Optimization of Lamb modes induced by laser can be achieved by adjusting the spatial source distribution to the mode wavelength (). The excitability of Zero-Group Velocity (ZGV)…
Investigation of interfacial stiffnesses of a tri-layer using Zero-Group Velocity Lamb modes
Sylvain Mezil, François Bruno, Samuel Raetz +3
Zero-Group Velocity (ZGV) Lamb waves are studied in a structure composed of two plates bonded by an adhesive layer. The dispersion curves are calculated for a Duralumin/epoxy/Dural…
Non-destructive testing of composite plates by holographic vibrometry
Francois Bruno, Jérôme Laurent, Claire Prada +3
We report on a wide-field optical monitoring method for revealing local delaminations in sandwich-type composite plates at video-rate by holographic vibrometry. Non-contact measure…
Holographic imaging of surface acoustic waves
Francois Bruno, Jérôme Laurent, Daniel Royer +1
We report on an experimental demonstration of surface acoustic waves monitoring on a thin metal plate with heterodyne optical holography. Narrowband imaging of local optical pathle…
Phase-sensitive narrowband heterodyne holography
Francois Bruno, Jean-Baptiste Laudereau, Max Lesaffre +2
We report on amplitude and phase imaging of out-of-plane sinusoidal surface vibration at nanometer scales with a heterodyne holographic interferometer. The originality of the propo…
