Abstract:

An experimental investigation of unipolar arcing at atmospheric pressure was conducted using Aluminum 2024 and glass slides with a thin coating of pure aluminum. The plasma was produced on the surface using a neodymium-glass laser in the Q-switched mode. It was found that the power density required for the onset of unipolar arcing was similar to that of samples irradiated in a vacuum, although the size and density of the resulting craters were significantly different.
