Abstract
Intense visible laser emission on the 0-3 transition of the N2 (C→B) band at 405.9 nm has been observed by exciting Ar/5-10% N2 (pTOTAL ≈2000 Torr) gas mixtures with a long-pulse (∼0.5 μs) electron beam of cylindrical symmetry. The experimental apparatus consists of a coaxial diode of 50 cm length and 250 cm3 anode volume driven by a low inductance, ∼250-kV Marx generator. Lasing on the violet line occurs following bottlenecking of the 0-1 and 0-2 ultraviolet laser transitions. With ∼0.8% output coupling at 406 nm, a maximum output energy of 2.2 mJ in a 200-ns FWHM pulse has been obtained in the violet which is comparable to that extracted (for optimum mirror transmission) on the 358- and 380-nm UV laser lines.
