| Abstract: | The properties of laser-induced cavitation bubble collapse sound waves during the high-power laser and matter interaction in different viscous liquids were investigated by the piezoelectric transducer(PZT)hydrophone.The experimental results indicate that the liquid viscosity has an obvious influence on laser-induced cavitation bubble collapse sound waves,larger viscosity makes the intensity of sound waves more feeble,and the peak of frequency becomes higher and higher. |
