Time-Resolved Shadowgraphy of Electrical Discharges Triggered by Laser in Air

Laser-triggered electric discharges were diagnosed using fast time-resolved shadowgraphy. A focused laser beam produced a plasma between two parallel plates connected to a high-voltage supply. This plasma, in turn, triggers the main arc between the plates. It was found that arcing occurs at about 400 after laser firing. The breakdown mechanism responds to a… CONTINUE READING
