Abstract
A method for inducing a controllable jet in a transparent liquid is disclosed. The method comprises providing a gas-liquid interface, providing a laser source and generating a beam comprising a sequence of laser pulses, and focusing the beam to a target location within the liquid at a predetermined distance from the gas-liquid interface and creating a plurality of cavitation bubbles, yielding a jet directed away from the gas-liquid interface. Other methods and apparatus are also described and claimed.

A method for inducing a controllable jet in a transparent liquid, comprising:
- providing a gas-liquid interface;
- providing a laser source and generating a beam comprising a sequence of laser pulses;
- focusing said beam to a target location within the liquid at a predetermined distance from the gas-liquid interface and creating a plurality of cavitation bubbles.
An apparatus for inducing a controllable jet in a transparent liquid, the apparatus comprising:
- a support of liquid with a gas-liquid interface;
- a laser source for generating a beam comprising a sequence of laser pulses;
- a focusing optics for focusing a said beam to a target location within the liquid at a predetermined distance for creating a plurality of cavitation bubbles, yielding a jet directed away from the gas-liquid interface;
- a relative displacement facilitator for facilitating relative displacement between the objective focal point and the gas-liquid interface for setting a predetermined distance between the objective focal point and the gas-liquid interface.
