Abstract

Using the notion of a source function, which describes the power deposited inside irradiated particles, we study the internal motion of irradiated water droplets by an intense laser pulse. The spatial distribution of the absorbed energy allows us to investigate 2-D hydrodynamic motion of the droplet. We find shock waves within the droplet and jets of vaporized material moving into the surrounding medium.
