Circuit modelling of a two-stage Blumlein-driven TEA- laser

This is the authors' abstract. We don't add key points for this paper.

The operation characteristics of a two-stage Blumlein circuit (TSBC), which can increase the output energy of a TEA- laser by 100% without embarking on spark-gap miniaturization, are investigated using a discharge-coupled circuit model. This circuit model predicts that a TSBC can produce a laser-channel breakdown voltage of up to , as compared with computed for a one-stage Blumlein circuit (OSBC), where is the charging voltage. Although the gain in the breakdown voltage is only 25%, it significantly increases the laser-channel current and input power which, when compared with computed values for an OSBC, are enhanced by 2.3 and 2.6 times respectively. The computed input power, as a function of , is correlated to that of the measured laser output.
