Abstract : The development of gas lasers has provided the experimental atomic physicist with a new tool for the selective probing of atomic energy levels. This dissertation describes the development of a gas laser system for the measurement of atomic parameters. The system has been applied to the measurement of transition probabilities and collision excitation cross sections in neon. The experimental technique utilizes a helium-neon laser oscillating at 3.39 microns --3s2-3p4 (Paschen notation) -- to perturb the population density of the 3s2 level in a neon discharge. This perturbation is coupled to the 3s3 neon level through non-radiative collision induced transitions. (Author)
