Abstract : The purpose of this research was to investigate the quenching of the 4 doublet D(3/2) - 4 doublet D(5/2) states of copper. These are the terminal states involved in the copper laser in which stimulated transitions take place from doublet P to doublet D states. The approach which was adopted involved the introduction into the copper discharge system similar to that employed in the actual laser, another atomic species with resonance states in the vicinity of the Cu states, to which excitation transfer from the doublet D states could easily take place. Such is the case with the resonance states of potassium and of cesium. The seven months over which the contract extended (December 1st 1972 to June 30th 1973) were spent in the design and construction of the experiment and in some preliminary tests of the apparatus and of the discharge.
