Abstract :
The laser-induced bubble sound waves during the high- power laser and matter interaction in liquid are investigated by experiments. By the piezoelectric transducer (PZT) hydrophone, laser-induced cavitation bubble collapse sound waves at different conditions are measured by experiments. The signals of sound waves are analyzed based on fast Fourier transform (FFT).The investigation results show the peak of frequency is reflected by the radius of laser- generated bubble, and the frequency peak decreases with the radius increasing. The results are of values in theoretical and applied research in cavitation noise.
