Acoustical measurement of solid state non-linearity: Application to CsCdF3 and KZnF3
Journal of Sound and Vibration, 1983Abstract Combination of the results of two sets of measurements on the same crystalline samples of CsCdF3 and KZnF3 has made possible the evaluation of the third-order elastic (TOE) constants of these two fluoroperovskites. In the first technique the hydrostatic pressure dependence of the velocity of ultrasonic waves of different propagation and ...

Q-factor of acoustic modes of a solid-state resonator at low temperatures
Measurement Techniques, 2011The acoustic characteristics of a cylindrical sample made of an aluminum alloy (model of gravity detector) in the course of cooling to temperatures on the order of the boiling point of liquid helium are studied. A specialized cryostat with working chamber having a large volume is presented.

Use of Solid-State Acoustic Transducers in Communications
The Journal of the Acoustical Society of America, 1971Semiconductor and solid-state devices have been used extensively to measure and generate stresses and stress waves in solids, liquids, and gases. Semiconductor devices have been used as strain gauges to measure strains and to respond to acoustic pressures. p-type silicon has a guage factor of over 100 times that of a metallic strain gauge. By using the

Acoustic intensity modulation of solid-state lasers by means of a rocking mirror
Soviet Journal of Quantum Electronics, 1984Intensity modulation was produced in ruby and YAG:Nd3+ lasers by varying the angle of inclination of one of the resonator mirrors (rocking the mirror) at an ultrasonic frequency. Modulation occurred at twice the frequency of the excited mirror vibrations, the average intensity of the emission spikes simultaneously increased by a factor of more than 10,

Acoustics of wet porous media with evaporation/condensation
The Physics of FluidsThis paper investigates acoustic wave propagation in wet rigid-frame porous media accounting for evaporation and condensation. At equilibrium, the solid walls are covered by a thin water film, and water vapor in the air is at its temperature-dependent ...

Soviet Physics Uspekhi, 1992
The experimental results in the field of laser generation of acoustic pulses of duration less than 1 ns are reviewed. The various physical mechanisms of optoacoustic conversion are analyzed theoretically. Possibilities are shown for shortening the duration of optoacoustic pulses by increasing the intensity of the laser exposure.

Realization of chiral two-mode Lipkin–Meshkov–Glick models via acoustics
Reports on progress in physics. Physical SocietyThe chirality-controlled two-mode Lipkin–Meshkov–Glick (LMG) models are mimicked in a potential hybrid quantum system, involving two ensembles of solid-state spins coupled to a pair of interconnected surface-acoustic-wave cavities. With the assistance of

ASME 2023 32nd Conference on Information Storage and Processing Systems, 2023
Abstract A multilayer ceramic capacitor (MLCC) vibrates when a pulse signal or a periodic signal is applied due to the piezoelectric characteristics of the MLCC, which causes structural resonance and acoustic noise in the Solid State Drive (SSD). Since MLCC is attached to the SSD through solders, the vibration of MLCC can be treated as a

Two-frequency acoustic modulation of the intensity of radiation emitted by solid-state lasers
Soviet Journal of Quantum Electronics, 1982Internal two-frequency modulation of the intensity of radiation emitted by ruby, neodymium glass, and YAG lasers was achieved by simultaneous excitation of a 5–25 MHz surface acoustic wave on one of the resonator mirrors and longitudinal ultrasonic vibrations of 20–100 kHz frequency of the other mirror.
