Longitudinally Excited N₂ Laser Pumped by Lamplike Discharge

Nitrogen laser oscillation is observed in a lamplike discharge within a longitudinal excitation tube. The laser consists of a 30-cm-long Pyrex glass tube with ail inner diameter of 2.5 film and a step-Lip transformer directly coupled to the discharge tube without a high-voltage switch. The excitation is produced by wall-coupled discharge. The laser Output energy is 1.7 mu l at 12 Torr (1.6 kPa) and 40 Hz when applying a slow-rising Voltage Pulse of 37 kV (rise time of 572 ns).
