Abstract

The high-repetition-rate operation of a transversely excited atmospheric CO2 laser pumped by an all-solid- state exciter consisting of a three-stage magnetic pulse compressor has been tested. At a repetition rate of 140 pps, an average laser power of 1.2 kW was obtained with an overall efficiency of 7.6%. For further increase of the repetition rate, influence of density perturbation on laser performances (discharge stability, laser output energy and beam quality) have also been investigated.
