Abstract

This article presents the visualization of the cavitation bubble generated with laser-induced breakdown. The cavitation bubble is generated with 532nm Nd: YAG laser beam, 10ns short with two different optical setups. Here, we use direct optical way focusing the laser beam, and reverse way base on the focusing mirror. We are using different laser light power and visualize the laser probe in correlation of bubble characteristics. The visualization is set on long-distance microscopy and shadowgraph lightening method. The main goal of the research is to set the optical setup for the laserinduced breakdown and to create the calibration relation curve for the bubble size dependence on the input energy of the laser beam. This calibration curve is related to the lifespan of each bubble, or the group of bubbles.
