Abstract

The electrical discharges which exist in a gas-pulsed laser (ignition system and laser tube) constitute an additional problem to the study of the whole laser system. This is due to their time-dependent behavior during the discharge. An electrical discharge can be symbolized as time-dependent resistance and inductance in the laser electric circuit. The analysis of the circuit is impossible if the resistance and inductance functions in relation to time are not known. This work illustrates a very easy way of finding the resistance and inductance functions in relation to time. This can be achieved by measuring only the waveform of the voltage across the capacitors of the system. By combining this waveform with the differential equation of the system performance, the evolution of the resistance and the inductance in relation to time can be determined. The quantities which can be calculated after that, in relation to time, are the oscillatory frequencies, the damping constants as well as the impedances of the discharges.
