Abstract : During this reporting period, investigations were conducted leading to the design, construction, and test of two CO2 TEA laser systems: (1) A modular CO2 TEA laser rangefinder, and (2) A high pulse repetition rate (PRF) waveguide CO2 Tea laser transmitter. For these two high performance systems, emphasis was placed on miniaturization and ruggedization. As a result of this work, fieldable hardware was developed and tested. During the development of the lasers, a considerable amount of research into the basic operating parameters of the devices was performed. For the 50-mJ TEA laser rangefinder, preionization and sealed-off lifetime techniques were investigated. For the small waveguide TEA laser, operating at atmospheric pressure, the optimum parameters of gas mix, gas flow rate (for high PRF), energy input, resistive electrode loading, and discharge current phase shape were determined.
