Abstract
Details of an experimental investigation of the small signal gain and saturation parameter of a 10 kW CW photoinitiated, impulse-enhanced, electrically excited (PIE) CO2 laser are presented. Measurements were made as a function of several device operational conditions, such as gas pressure, input electrical power, pulser ionisation and flow velocity. Gain profiles were also obtained, both from anode to cathode, and in the direction of gas flow. The results document the effectiveness of the PIE excitation technique, while providing detailed information on the gain medium. Such data are essential to the design of an efficient optical extraction system.Keywords
