Abstract : A neutral rare gas laser has been built, and used to produce continuous wave output in the near- and mid-infra-red regions. The He-Xe mixture was excited by a hollow cathode discharge, and line-tunability was achieved by use of a diffraction grating as the rear optic. Two of these lines, viz. 2.026 and 3.894 micrometers, are of particular interest due to their location in the 2 and 4 micrometers atmospheric windows, respectively. A parametric study was conducted to determine the optimum working regimes (total pressure, partial pressure ratio, current, output coupler transmission, and grating). This General Document is a paper presented at the Australian Conference on Optics, Lasers and Spectroscopy (ACOLS), held at the University of Melbourne in December, 1993. (jg)
