Abstract

Laser acoustic is a new way to generate underwater sound sources. Photoacoustic signals have the advantages of high sound intensity, narrow pulse, wide spectrum and long-range excitation. In this paper, the related characteristics of vaporization mechanism of laser induced acoustic are studied. The characteristics of vaporized acoustic signal and photoacoustic conversion efficiency are theoretically analyzed. The principle experiment of laser induced acoustic is designed. The waveform and spectrum of acoustic signal are analyzed. The result of research can provide a reference for the optimization of laser acoustic conversion efficiency.
