Pulse Width Measurement of Sonoluminescing Air Bubbles in Various Solutions using a Time-Correlated Single Photon Counting Technique

Abstract

The pulse widths of light from sonoluminescing air bubbles in various solutions were measured by a time-correlated single photon counting (TC/SPC) method to investigate the effect of density on sonoluminescence characteristics. The measured values of the pulse width were about 150∼190 ps. No appreciable difference in the pulse width and the bubble behavior for the sonoluminescing air bubbles in various solutions was found even though they have quite different density values varied from 1000 kg/m³ to 1800 kg/m³.
