Abstract : The report discusses the experimental results and optimization of a relatively high-power, high-efficiency CW gas laser utilizing a dc excited discharge with a flowing combination of carbon dioxide, helium, and nitrogen as the active laser medium. Continuous laser power output of 126 watts has been measured from a system of 4.7 cm diameter by 2.4 meters long. Details of the various cavity configurations, reflector materials, power coupling-out methods and current characteristics of the discharge are discussed. A 90 degree folded design cavity is described including some intra-cavity Q-switching experiments. These experiments are part of a continuing study of the technology concerning design, construction and optimization of CO2 lasers. (Author)
