Abstract
An X-ray preionization pulse laser comprises a laser tube in which a pair of main electrodes are disposed to face each other. Pulse discharge between the main electrodes excites a laser medium, thereby obtaining laser oscillation. The laser has a sealed vacuum chamber in which a sliding discharge area is arranged. The sliding discharge area produces sliding discharge that generates X-rays for preionizing the laser medium before the main discharge occurs for laser oscillation.
