Single bubble sonoluminescence: Investigations of the emitted pressure wave with a fiber optic probe hydrophone

摘要: In single bubble sonoluminescence (SBSL) in addition to the short light pulses, emits collapse phase a pressure wave that can be measured with fiber optic probe hydrophone high spatial resolution (100 \ensuremath{\mu}m) and rise time of 5 ns. systematic study we have characterized width amplitude emitted dependence driving pressure, gas concentration, water temperature. The acoustic increases increasing concentration from about 7 ns more than 30 stability range, where SBSL observed. contrast intensity, temperature has only little influence on wave. Theoretical considerations using Gilmore equation show good agreement experimental data.
