The Nitrogen Ion Laser
Abstract
The characterization of the 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 0.3A. The pumping ion, He2(+), was produced by discharge of a fast-pulsed electron beam gun, APEX-1, into 7 atmospheres of a mixture of helium and nitrogen. Excitation current densities were 1.4KA/sq cm at 1 MV over a 1 x 10 cm transverse geometry. Efficiency is discussed.
