Laser-induced bubble was generated by YAG laser bombarding the metal target in the water at different venturi inlet pressures. The movement of laser-induced bubble in venturi was recorded by a high-speed video system. Characteristics of flow field in venturi and bubble collapse were analyzed by computational fluid dynamics. Results show that the process of laser-bubble moving in venturi can be classified into four periods: generation, extrusion, initial collapse, and collapse period. Bubble collapse depends on the state of flow field. Bubble does not collapse when the flow is in laminar state. However, bubble collapses when the flow is in turbulent state. The collapse phenomenon becomes prominent with increasing turbulence intensity. The bubble collapse at a fixed point can be realized in the laser-bubble generation and movement system.
