The effect of preionization on a dielectric-electrode discharge in CO/sub 2/ laser media is described. Compared to previous devices without preionization, specific energy extraction has been increased approximately threefold to 6 J/1 atm and gas pressures for stable operation are increased from below 1 atm to above 2 atm. With preionization, pulse-to-pulse repeatability for a 0.5-Hz repetition rate under static gas conditions is greatly enhanced compared to operation without preionization in the present device. These results compare favorably with those obtained in conventional metallic-electrode discharge transverse electric atmospheric (TEA) lasers.
