Abstract
Measurements and investigation were made on the development process and the radiated acoustic wave signal of the two-bubble which is generated by high-power laser reacting with liquid, using the high-speed camera and the high-frequency measurement hydrophone. The result from analysis shows that, the reduced distance between two bubbles and increased laser energy applied on them cause increased interaction between two bubbles resulting in graduallyy prolonged period of two-bubble collapse and gradually increased pressure of cavitated acoustic wave; at the same time, with increasing distance between bubbles, the interacting force between bubbles disappears and both bubbles takes on the characteristics of a single bubble.
