An experimental effort was undertaken to obtain laser action from a high-power pulsed gas laser operating at a wavelength that falls in the atmospheric window between 3 and 4 microns. The major effort was concentrated on the 3.39 micron transition of He-Ne. The experimental procedures involved microsecond-duration high-voltage pulsing, high gas pressures, high gas ratios, and large bore tubes. The maximum output power obtained was 42 milliwatts. This output, which is relatively low in terms of objectives, appeared to be limited primarily by streamer development in the plasma at high inputs and high pressures. It was determined that output power did increase with increased pressure and pressure ratio. Included are suggestions for overcoming some of the limitations encountered. Author
