Spatial separation and motion of electric charges arising due to the interaction of high-power IR laser radiation with water

We have studied temporal and amplitude characteristics of the electrical signal arising under irradiation of the free water surface by a 2.94-μm high-power laser. The investigations have been conducted using a specially designed electrode system, which makes it possible to record the motion of the electric charge after the end of the laser pulse. We have measured the dependences of the signal parameters on the radiation energy density at the water surface.
