Abstract : The report presents experimental data on the output power and efficiency of the sealed-off CO2 laser as a function of discharge current, the initial fill pressures of CO2 and He, and the tube diameter. The optimum fill pressure of pure CO2 for maximum power output and efficiency was found to be approximately 5/d Torr, where d is the tube diameter expressed in cm. At this pressure the optimum current for maximum power output was about 7d mA. The output power can be increased by a factor of five with the addition of about 10 Torr of He. With He, the optimum current for maximum power output was approximately 18d mA. (Author)
