Abstract

Acoustic signals generated in water by terawatt (TW) laser pulses undergoing filamentation are studied. The acoustic signal has a very broad spectrum, spanning from 0.1 to 10 MHz and is confined in the plane perpendicular to the laser direction. Such a source appears to be promising for the development of remote laser based acoustic applications.

摘要

研究了太瓦（TW）激光脉冲在水中丝状化产生的声信号。该声信号具有非常宽的频谱，范围从0.1到10兆赫兹，并且局限于垂直于激光方向的平面内。这种声源对于基于激光的远程声学应用的发展似乎很有前景。
