High power CO2-laser at 100 Hz rep-rate

The pulsed power issues in power conditioning for high power CO ₂ lasers are related to the peak pulse voltage at the laser cavity, the pulse duration, and the repetition frequency. For an electron beam sustained CO₂ laser system with an average output power of more than 15 kW, the pulse voltage at the modulator approaches the 50 kV level with a pulse duration ranging from a few to a couple of ten microseconds or more. This paper presents the design of the power conditioning equipment and the experimental verification of a repetitively-pulsed high power CO₂ laser with an output power of more than 15 kW, a pulse duration of 10 μs, a pulse repetition rate of up to 100Hz and a pulse train of 1000 shots
