Predictions for Upscaling Sonoluminescence

Abstract

Only a small fraction of the high-dimensional parameter space that governs the occurrence of stable single-bubble sonoluminescence (SBSL) has been explored so far. We predict that decreasing the acoustic driving frequency $f$ upscales SBSL. More specifically, at $f = 5 kHz$ we expect more than 100 times as many photons per flash as at $f = 20 kHz$ and a flash width of about 1000 ps. The application of lower frequencies has to be assisted by reducing the partial inert gas pressure of the dissolved gas (e.g., stronger degassing) to maintain diffusive stability of the bubbles.
