Abstract :
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
