ABSTRACT:
An apparatus for initiating electrical discharge in a gas transport laser having two or more sets of electrodes comprises a pulse generator connected to both sets of electrodes. The pulse generator comprises an alternating current (AC) source connected to the primary windings of two transformers having secondaries connected to the sets, respectively of electrodes. By energizing the transformers after the application of a direct current (DC) voltage across the electrodes of each set, a discharge across the sets of electrodes occurs simultaneously for a balanced starting of the lasing action.
The invention also comprehends the method of starting a laser having a plurality of sets of electrodes consisting of the steps of applying a DC potential across each set of electrodes and transmitting at least one voltage pulse simultaneously to one of the electrodes of each set to produce simultaneously an electrical discharge between all sets of electrodes.
