Abstract
A new discharge circuit implementing the magnetic-spiker sustainer excitation is reported that overcomes the large, bulky and heavy size of the transformer for a high repetition rate CO2 laser. The new discharge circuit reduces the rms current flowing through the saturable core pulse transformer. An output of 5J and approx. 13% overall efficiency has been obtained from a helium-free gas mixture at 400 mbar on a working TE CO2 laser. The circuit also allows operation of the discharge at reduced voltage and extends the excitation current pulse durations (approx. 7 µs) over which arc-free discharges can be formed.
