The Nitrogen Ion Laser
Abstract
The first nitrogen ion laser pumped by charge transfer from He2(+) is reported in this work. Intense laser emission in the violet at 427 nm has been observed and found to have a linewidth less than 0.3 nm. The pumping ion, He2(+) , was produced by discharge of a fast-pulsed electron beam gun into 7 atmospheres of a mixture of helium and nitrogen. Excitation current densities were 1.4 KA/sqcm at 1 MV over a 1 x 10 cm transverse geometry. Under these conditions, the efficiency of the emission of 427 nm laser radiation was found to be 1.8% relative to the energy lost by the electron beam in the radiating volume.
