摘要：
The directionality of the sound generated by laser-induced liq-uid breakdown in water is investigated both theoretically and experimen-tally.The theoretical analysis is based on the following model.A seriesof small spherical cavities including plasma are homogeneously distributedon a short straight line segment and every such cavity may be consideredas a point source radiating acoustic impulse.Theoretical expressions ofthe relations between the amplitude and width of acoustic impulse and thereceiving direction are given.Experimental results are in agreement withtheoretical predictions.
