Abstract

The directivity of the sound fields excited by laser-induced liquid breakdown is studied through theory by using fundamental theories of acoustics. So a conclusion is drawn that directivity calculated by theory. The directivity of the laser-induced sound field is related to energy range and radiation area of the laser beam.
