( 71Kb ) Abstract Recent studies have shown that the measured flash widths from single and multibubble sonoluminescence are in subnanosecond or even picosecond regime. Here, we provide conclusive evidence for the existence of nanosecond multibubble sonoluminescence. This has become possible by our ability to find a medium from which exclusive sodium D line resonance radiation as a form of sonoluminescence is possible. The measured flash width of this emission is found to be in the range of tens of nanoseconds and is sensitively dependent on experimental parameters. Our finding is important since all the earlier pulse width measurements have been limited to emission with the physical source or species responsible for observed optical radiation not being clearly identified. We propose that the presently observed resonance radiation is from ‘‘soft’’ bubble collapse as analyzed by V. Kamath et al.

Phys., Addenbrooke's Hospital, Cambridge, UK Abstract. For pt.1 see ibid., vol.33, no.11, p.1239-48 (1988). Sonoluminescence, produced when a therapeutic ultrasound generator operating at 1 MHz was used to insonate a tank of water, was detected using a photomultiplier tube and analysed using pulse height analysis. Spectra of the number of counter per second were obtained for the complete range of observed pulse heights, under exposure conditions similar to those used in clinical practice. Water containing different concentrations of dissolved gases and an agar solution were investigated during the course of the experiments. Measurements were made to establish a threshold for sonoluminescence and the total sonoluminescent light output from tap water insonated with continuous wave ultrasound at 1 W cm was estimated. The density of free radicals produced under these conditions was also estimated. The effects of temperature and duty cycle were investigated over the range 22-45 degrees C and pulsed regimens produced more sonoluminescence than continuous wave ultrasound over a significant part of the pulse height spectrum.

+ Visit NASA.gov + Visit Glenn Research Center +Home As part of basic and applied research on advanced instrumentation technologies, NASA GRC is examining applications for sonoluminescence, the ultrasonically-produced glowing bubbles hotter than the sun. Image right: Multi-Bubble Sonoluminescence demonstrated at NASA Glenn Research Center in a 50 ml flask of distilled water. Credit: NASA Sonoluminescence has risen in the last decade to be a source of interest to those outside of the ultrasonic community in an effort to either understand the effect or to utilize some of its more interesting properties. The phenomena is defined as being the generation of light energy from sound waves, first discovered in the 1930’s as a by-product of early work on sonar. Originally thought to be a form of static electricity, this glow recently was found to be generated in extremely short duration flashes of much less than a billionth of a second by collapsing microscopic bubbles of air. The temperature generated in the collapsing bubbles is at least four times that of the surface of the sun.

Intended to promote an understanding of fundamental shock physics, to highlight current research in the many related fields, and to discuss the application of various aspects of shock physics, the conference provides an international forum for technical exchange among scientists, engineers, academic professionals, users, and industrialists. Sonoluminescence. Sonoluminescence is a phenomenon which involves the conversion of acoustical energy to optical energy arising from the nucleation, growth, and collapse of gas-filled bubbles in a liquid. The process of generating light appears to be extremely rapid and represents a remarkable -degree of energy concentration, i.e., as high as 12 orders of magnitude. Recent experimental -advances have pro-duced a single acoustically levitated sonoluminescent air bubble with unanticipated temporal and spectral properties, which are inconsistent with existing models of sonoluminescence.
