This final engineering report summarizes the work performed during a one-year program culminating in the development of a compact, 200 watt, gas transport laser head, for ultimately airborne applications. The report describes the design, circulated, cooled gas through a large 400 cu cm glow dischargeoptical cavity volume, over 200 watts of cw power, at a single wavelength 10.59 micrometers was generated by the laser head, with a total head efficiency of 6. The laser head weighs less than 100 pounds, and has a maximum linear dimension of 24 inches and a volume of 3 cu ft. The stable, nine-pass z configuration folded optical resonator cavity, vibrationally isolated from the main vacuum enclosure, produced a TEM 00 mode beam pattern with good beam amplitude and directional stability, at maximum power. A conceptual design of an entire airworthy laser system based on the head developed during the program is also presented in the report.
