Electric-discharge-pumped nitrogen ion laser

Abstract
A preionized transverse electric‐discharge‐pumped N+2 charge‐transfer laser oscillating on the (B2Σ+uX2Σ+g) transition of N+2 is reported. Peak power of 180 kW in a 8‐nsec FWHM laser pulse has been obtained with a 0.1% mixture of N2 in helium at a total pressure of 3 atm. The most intense laser oscillation occurs on the (0,1) vibrational transition at 427.8 nm.
