  • 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 is dilated and pressed in the process of the water column motion initiated by laser pulse. Tenfold increase of electric signal is achieved if the thin water layer is presented between the upper border of the cell and quartz plate which closes the cell and touches the upper surface of water column.
