title = "Application of laser-induced acoustic method on air-underwater communication",
abstract = "Laser-induced acoustic (LIA) technology is a possible way of communicating from an air-based platform to the underwater target in the sea. The present paper introduces a method of LIA which works in the optical breakdown mechanism. Acoustic signals with high energy were generated in the optical breakdown mechanism of a Nd: YAG laser having pulse widths about 10 ns. A DFB-FL hydrophone was designed to receive the LIA signals for the various repeated frequency of the pulsed laser. It was found that LIA signals with repeated frequency ranging from 1 to 20Hz can be detected clearly, which demonstrated the feasibility of across air-underwater communication by using LIA technology. Simulation of LIA in a distance of 400m between laser spot on the water surface and the hydrophone was performed by the COMSOL Multiphysic software. The simulated results show the communicated ability of LIA technology in the long distance.",
