The expansion and contraction of cavitation bubble in liquids with different ambient pressure were investigated experimentally, which are compared with the analyses based on Rayleigh-Plesset equation. In the experimental study, cavitation bubble was induced by the high-power laser and matter interaction in liquid, laser-induced cavitation bubble callapse in liquids with different ambient pressure were detected by high-speed video and high-frequency hydrophone. The results show that the ambient pressure has obvious influence on the bubble oscillation. Increasing the ambient pressure speeds up bubble collapse process, decreases the oscillating cycle and maximum bubble radii ,and shortens the time of expansion and contraction of cavitation bubble.
