The importance of molecular complexes in gas discharge lasers has long been recognised, and indeed they are the essence in excimer lasers. For other discharge lasers operating with gas mixtures, for example metal vapour lasers, the role of molecular complexes in the laser discharge has hardly been addressed. In this work the emission from a cw multi-colour hollow-cathode HeCd+ laser has been investigated spectroscopically, and emphasis was placed on the detection of molecular bands. Specifically the presence of He2∗ in the laser discharge was confirmed which is thought to play a major role in the generation of the green laser lines. Emission bands attributed to the Cd2∗ metal dimer were identified; however, this dimer does not seem to be of importance in the laser process. In addition to the He2∗ and Cd2∗ emission strong molecular continuum bands, exhibiting gain, were observed which accompany all laser lines; these can only be interpreted as originating from transitions in the ionic complex (HeCd+)*.

This paper presents results of measurements of the electron energy distribution function (EEDF) in the range 0 - 40 eV, and the electron density and the space potential for the helium plasma of a longitudinal discharge in a hollow cathode as used for He-inert gas and He-metal vapour lasers. The results show that the EEDF and also the mean electron energy, the electron density and the plasma potential differ from those typical of the transverse hollow-cathode discharge.
