Abstract We have numerically analyse the stability of sonoluminescing bubbles in a relatively wide range of experimental parameters and have determined the stable domains for single-bubble sonoluminescence in the Pa-R0 phase diagrams. We map the phase diagrams when the frequency of the driving pressure f is 26.5kHz at the ambient pressure P0 of 2 and 0.5atm, and the frequencies 10 and 1kHz at 1 atm. When the frequency is lowered to 1kHz, the ambient radius R0 can be as large as 20μm.
