Underwater acoustic wave generation by filamentation of terawatt ultrashort laser pulses
, 2016 Acoustic signals generated by filamentation of ultrashort TW laser pulses in water are characterized experimentally. Measurements reveal a strong influence of input pulse duration on the shape and intensity of the acoustic wave.

Fundamental study on a thin-film ae sensor for measurement of behavior of a multi-pad contact slider [PDF]
, 1996 To study the fundamental dynamic characteristics of a multi-pad slider for contact recording, we developed a thin-film piezoelectric acoustic emission array sensor on an Si-suspension with an array pattern similar to that of contact pads.

Acoustic Emission: Establishing the Fundamentals
Journal of Research of the National Bureau of Standards, 1984 In the mid-1970's a program of fundamental research was initiated at NBS to improve the scientific understanding of acoustic emission. Many individual results of this research have been reported in the literature and are beginning to be incorporated in a new generation of acoustic emission instrumentation, in improved test methodologies, and in the ...

Decoherence in quantum dots due to real and virtual transitions: a non-perturbative calculation
, 2009 We investigate theoretically acoustic phonon induced decoherence in quantum dots. We calculate the dephasing of fundamental (interband or intraband) optical transitions due to real and virtual transitions with higher energy levels.
