Physical aspects of sonoluminescence from acoustic cavitation
- Abstract:
- The passage of an ultrasonic wave through a medium can sometimes result in the production of acoustic cavitation which is often accompanied by the generation of light; a process known as sonoluminescence or ‘light from sound’. A brief historical overview of early sonoluminescence (SL) research is presented, followed by a phenomenological description of the physics of cavitation bubble fields. Many of the published results describing the features of SL (pulse duration, phasing, spectra, etc.) are inconsistent and sometimes contradictory. However, recent studies of sonoluminescence from individual, radially pulsating bubbles draw a consistent picture. Single-bubble SL flashes occur once every acoustic cycle and coincide precisely with bubble collapse. The duration of the flash is believed to be ⩽50 ps and the emission spectra indicate substantial heating of the bubble interior. These results suggest that the primary mechanism for single-bubble sonoluminescence is the rapid heating of the interior of the collapsing bubble.
