Abstract

Laser breakdown in liquid induced by ultrafast high repetition rate laser pulses tightly focused close to a flat or curved surface of a liquid-gas boundary is investigated. It is shown, that in case of focusing a laser beam close to the liquid - gas boundary a low divergent jet appears consisting of liquid and bubbles of micron size and less. The direction of the jet coincides with the perpendicular to the boundary surface, passing through the objective focal point. The length of the jet depends on the kind of liquid, laser pulse parameters and the distance between the beam focus point and the liquid - gas boundary and may reach several centimeters.
