Abstract : The discovery of the HCN laser has given scientists, for the first time, an inexpensive coherent source in the submillimeter region of the spectrum. Experiments are described there various chemicals were added to the basic laser fuel, CH3CN (acetonitrile), in the HCN laser. Laser output power at 337 milimiters wavelength and current threshold, (minimum current necessary for oscillation) were monitored. Results include increased power and efficiency with the addition of CO2 or O2 to the discharge. Experiments also include the characterization of the HCN laser output over a wide range of pumping speeds. Increased pump speed resulted in increased power; however, power saturation occurred at higher pumping speeds. From these results one can obtain insight into the basic mechanism of the HCN laser and develop possible means for improvement. (Author)
