Abstract

This paper presents a liquid jet caused by a laser-induced cavitation bubble in thin films (height varies from micro to nanometers). The dynamics is highly depending on the thin film's dimension and viscosity. The penetrating axial jet can be enhanced by increasing the laser energy or decreasing the distance between the laser focus and the targeted gas bubble surface. In the microchannel, strong shear stress ruptures part of the gas bubble and Rayleigh-Plateau instability further shattered it into small bubbles. While in the nanochannel, the nanojets can accelerate femtoliter liquids with thickness of hundreds of nanometers.
