Abstract
A small-scale (100-cm3 discharge volume, 2-J output) x-ray preionized CO2 TEA laser is described. The laser utilizes an automatic switching technique to synchronize the flash x-ray burst (50-100 kV) and the main discharge (~50 kV) 300 ns later. Two types of cathode have been used in the x-ray preionizer—a corona plasma and a carbon fiber cold cathode. Both produced comparable amounts of ionizing x rays, although the emission from the corona plasma was more uniform.
