<P>PROBLEM TO BE SOLVED: To obtain an effective defoaming effect by directing a pulsed sound wave generated by impact caused by laser-induced breakdown to a liquid surface using an acoustic waveguide. <P>SOLUTION: A reflected wave of the pulsed sound wave generated by impact 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 differences in time in which the reflected wave in each traveling direction arrives at the opening part are reduced. <P>COPYRIGHT: (C)2012,JPO&INPIT |
