Power scaling of printed-circuit-board preionized TEA CO2 laser up to 3.6 kW

摘要

A high average power, high-repetition-rate TEA CO2 laser employing printed-circuit-board preionizer is described. The power scaling of this preionization configuration has been demonstrated. The average output power reaches 3.6 M at pulse repetition rate of 180 pps. Furthermore, the scaling-up ability of the rotating spark gap as high-voltage switch for high-average-power gas laser has been validated. (C) 2004 Elsevier Ltd. All rights reserved.
