Abstract

In gas lasers, the active medium in the laser channel is a weakly ionized plasma. The plasma properties of this active medium are expected to play important roles in the laser performances. Recently, studies in matching plasma impedances of the spark gap and laser discharge channels are reported for pulsed superradiant nitrogen lasers [1-3]. It is noted that the laser pulsewidth under goes a resonant narrowing when the impedances are matched in the charging circuit where the plasmas are modelled by an inductance- capacitance (L-C) parallel circuit phenomenologically [1].
