Ultrasonic pulses in a glass forming salt melt near T g . A time and space resolved study using interferometry

An optoacoustic experiment was set up to study generation, propagation, and damping of broadband acoustic pulses in the MHz region. The sound pulse front is detected interferometrically. The analysis is based on linear hydrodynamic theory and comprises diffraction of the sound pulse. To introduce re...
