| Abstract: | There are optoacoustic signals produced by pulsed laser in liquid,the laser energy and the intensity of optoacoustic signals have fixed relation.The varying relation is discussed between laser energy and intensity of optoacoustic signals.Thus a method is obtained to compute the breakdown threshold in liquid. |

| Keywords: | Optical breakdown Breakdown threshold Thermal expending |
