We have developed two high-efficiency, all-solid-state exciters for pumping TEA CO{sub 2} lasers, and experimentally proved their energy scalability, high-efficiency operation, and high repetition rate operation. The small-scale all-solid-state exciter of the two-stage magnetic pulse compressor was operated with an output transfer energy of 8.8 J/pulse and energy transfer efficiency of 78%, and the average CO{sub 2} laser power of 117 W was obtained at 250 pps using this exciter. The larger all-solid-state exciter of three-stage magnetic pulse compressor is ten times as large as the small one, and operated with an output transfer energy of 95 J/pulse and an energy transfer efficiency of 84%. With the larger exciter, a CO{sub 2} laser output of 9.1 J/pulse was obtained with a total laser efficiency of 8.1%. As a result, the scalability of the exciter for the CO{sub 2} laser has been demonstrated.
