The high-repetition-rate operation of a transversely excited atmospheric CO{sub 2} laser pumped by an all-solid-state exciter consisting of a two-stage magnetic pulse compressor has been tested. At a repetition-rate frequency of 1 kpps, an average laser power of 250 W was obtained. A maximum repetition rate of 1.1 kpps was limited by either the capability of the switching power supply (20 kW) or the turn-off time of the silicon controlled rectifier used (400 {mu}s). The energy transfer efficiency of the exciter was 75%, and the overall laser efficiency was 3.2%. By changing the amount of the available magnetic flux swing of the cores used, 30% regulation on the input energy was also achieved with a constant energy transfer efficiency of 78%.
