摘要： The objective of the present invention is to obtain an effective defoaming effect by directing a pulsed sound wave generated by shock caused by laser-induced breakdown to a liquid surface using an acoustic waveguide. A reflected wave of the pulsed sound wave generated by shock caused by laser-induced breakdown on an inner circumference face of the acoustic waveguide is directed to an opening part of the acoustic waveguide opposed to the liquid surface, and variations in periods of time in which the reflected wave in each travelling direction arrives at the opening part are reduced.
