Abstract

The comprehension of the performance of pulsed gas lasers requires knowledge of several parameters which are time dependent and consequently difficult to measure. These parameters are mainly influenced by the two electric discharges which take place during the laser performance, namely by the ignition system and laser tube. The present work illustrates a new method to determine the most fundamental of these parameters, the current. This can be achieved exploiting only the voltage waveform on which much concealed information exists about all the time dependent parameters. The revelation of these parameters can be achieved by further elaboration of the waveforms of the high voltages. This elaboration, in our case, leads to finding the current and is described in this paper. The method is applied to a simple RLC circuit, to a doubling, and to a C-to-C circuit and it is delivered from experimental errors existing in other methods achieving the best accuracy to date.
