Sonoluminescence refers to the light emission observed during the ultrasound-driven collapse of microbubbles . The presence of bubble clouds or multiple bubbles means that there is a group of bubbles or a steady-state bubble population that undergo collapse within an acoustic cycle leading to SL. The SL that is emitted from a multibubble field is referred to as MBSL. Under specific experimental conditions, it is possible to avoid the formation of a bubble field and acoustically levitate a stable, single bubble in a liquid. In this case, the bubble grows and collapses within one acoustic cycle. SL emission occurs in every acoustic cycle, which is referred to as SBSL.
The following sonoluminescence research projects are currently in progress in our laboratory.
