Abstract :

We present the first results of studying a pulsed (20 μs) discharge in nitrogen, which is produced by high-power (40 kW) focused beam of terahertz (0.67 THz) waves. The time dynamics of the discharge plasma glowing is studied in a wide range of wavelengths (300-650 nm) and gas pressures (0.5-350 Torr). An assumption is made about the determining role of long-living metastables of nitrogen N₂ (A³Σ_u⁺) in the observed dynamics of the discharge afterglow.
