Synchronous Picosecond Sonoluminescence
Abstract
If acoustic cavitation is produced in a liquid, the implosion of cavities can heat the internal contents of the bubble to incandescent temperatures. The electromagnetic emissions associated with this energy concentration can often be seen with the naked eye. This phenomenon, in which light is generated by sound is called sonoluminescence. A particular form of this phenomenon is called single-bubble sonoluminescence. This form is much easily to study because the fundamental bubble dynamics that leads to bubble collapse and the associated electromagnetic emissions can be ascertained. Also, in single bubble sonoluminescence it is likely that the bubble collapse is spherically symmetric, resulting in an amplification of this already violent phenomenon. The intent of this project is to investigate the phenomenon of single bubble sonoluminescence, and from knowledge gained here, to be able to provide useful information concerning the more general phenomenon of multiple-bubble sonoluminescence.
