Description

Ultrasonic transducers’ frequency and impulse responses can be determined if a test signal is available that can be adequately characterized. One such source is the expanding plasma bubble caused by a dielectric breakdown that occurs in the focus of the light from a pulse laser. The sound emanating from such a source can be predicted using a theory originally developed for macroscopic blasts if appropriate scaling of energy and plasma volume are included.
