Generation of Sound Waves in Water by a High Power Laser,

Abstract

Pressure waves generated in a lake (Brighton Dam Reservoir) have been Fourier analyzed with a hydrophone-heterodyne system in the range 0.0 to 125KHz. The frequency spectrum of the sound wave is discussed and compared to that of an explosion. High speed photographs of pressure transients generated in the laboratory are presented and discussed.
