Short-Pulse Laser and Plasma Surface Interactions.

Abstract

Unipolar arcing has been shown to be the primary plasma-surface interaction process when a laser produced plasma is in contact with a surface. Evidence of unipolar arcing was found on targets irradiated with neodymium laser pulses of 5 ns duration. The burn pattern of a defocused low irradiance laser pulse consists exclusively of unipolar arc craters. No other damage is observable. (Author)
