Abstract
Only a small fraction of the high-dimensional parameter space that governs the occurrence of stable single-bubble sonoluminescence (SBSL) has been exp lored so far. We predict that decreasing the acoustic driving frequency f u pscales 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 th e partial inert gas pressure of the dissolved gas (e.g., stronger degassing ) to maintain diffusive stability of the bubbles.
