| 摘 要： | 研究了脉冲HF激光与水柱表面相互作用下电信号的产生过程。电信号显示了与激光能量线性相关的峰值间有时间间隔的两峰结构,且第二个尖峰在水柱底部的蒸汽腔塌缩后出现。实验还显示电信号的幅值和激光脉冲照射过程中是否存在膨胀和挤压的薄水层密切相关。如果在电池上边缘和石英平板(石英板紧邻电池,并与水柱上表面相接)之间存在一薄水层,电信号强度会增加10倍。

| Abstract: | Generation of an electric signal under interaction of pulsed HF laser radiation with water column surface was investigated.It was found that the electric signal demonstrates pronounced a two-peak structure with time interval between peaks linearly depending on the laser energy.The second pike was determined to appear upon the collapse of the vapor cavity produced at the bottom of water column.It was also found that the amplitude of electric signal strongly depends on the presence of a thin water layer which... |
