In this paper, the design and operational characteristics of a UV-preionized high-repetition-rate (HRR) TEA CO_2 laser is described. A new spark array suitable for long-life, HRR operation was used as an efficient UV-preionization source. Using this preionizer, a closed-cycle HRR TEA CO_2 laser was obtained with average output power of 23 W at 7 pps with an electrical efficiency of 5%, and 10.5 W at 15 pps with an electrical efficiency of 3.2%. In sealed-off mode, the influence of gas degradation on laser performance was investigated by gas chromatography and an infrared gas analyser. The measured values of CO_2 dissociation rate caused by predischarge for pin spark array and by main discharge were 1.2 ppb/J and 18.7 ppb/J, respectively.
