ULTRASONIC EXPERIMENTS WITH PICOSECOND TIME RESOLUTION

Le Journal de Physique Colloques, 1985
We describe a new method which can be used to make ultrasonic measurements with picosecond time resolution. The method can be used to study samples in which the acoustic path length is very short and the ultrasonic attenuation very large. We describe the theory of the generation and detection process, and present some attenuation and velocity ...

Sub-Terahertz Monochromatic Transduction with Semiconductor Acoustic Nanodevices

, 2008
We demonstrate semiconductor superlattices or nanocavities as narrow band acoustic transducers in the sub-terahertz range. Using picosecond ultrasonics experiments in the transmission geometry with pump and probe incident on opposite sides of the thick ...

Thin-film optoacoustic transducers for the subcellular Brillouin oscillation imaging of individual biological cells [PDF]

, 2015
Mechanical characterisation and imaging of biological tissue has piqued interest in the applicability to cell and tissue biology. One method, based on detection of Brillouin oscillations, has already lead to demonstrations on biological cells using ...

Surfaces and thin films studied by picosecond ultrasonics [PDF]

, 1990
This research supported by grant FG02-86ER45367 is the study of the properties of solids by means of the picosecond technique. In this research we investigate both fundamental problems in phonon physics and lattice dynamics, and we also apply the technique to the non-destructive evaluation of thin-film microstructures.
