Abstract
Provided are a deforming method and device that use laser-induced breakdown. The provided method and device make it possible to shorten the focal distance, thereby improving laser beam convergence, and increase the utilization efficiency of sound waves that contribute to defoaming. Pulsed laser light is focused and irradiated into a space inside an acoustic waveguide (), thereby generating pulsed sound waves from the illumination point (). The pulsed sound waves propagate down the acoustic waveguide as plane waves, then propagate beyond an open end () as spherical waves, and break up a foam outside the open end of the acoustic wave guide.
