| Abstract |
An all solid-state pulser for the excitation of a high repetition-rate TEA CO2 laser is described. In contrast to convertional thyratron switched pulsers, the pulser is based upon a series connection of 5 fast switching thyristors. The high voltage is generated by a pulse transformer. The required pulse duration is achieved by application of a combination of parallel and series magnetic compression circuits. The power supply gives an average power of 8 kW, a pulse energy of 20 J and a repetition rate of 400 Hz. The peak voltage is 40 kV and the pulse duration is 500 ns. The power supply has been successfully operated on a dummy-load with an overall efficiency of about 70% at maximum power. The pulser has been operating with the CO2-laser at the maximum repetition-rate allowed by the laser of about 150 Hz. |
