Spectroscopic investigation of a gas-discharge pulse plasma of a Cu+Ne laser

An experimental study was made of the emission of spectral lines of Cu I, Cu II, Ne I, and Ne II. The absolute and relative intensities were investigated as well as the influence of the spontaneous radiation on the stimulated emission from a Cu laser. The integrated radiation spectrum of the plasma and its composition were also studied. The influence of some elementary processes on the simulated emission and the effect of the plasma composition on the laser efficiency were considered.
