Gain and optical extraction measurements in a pulser-sustained CO2laser

Operational data on small-signal gain, gain profile, and optical power extraction is presented for a photoinitiated impulse-enhanced electrically excited (PIE) CO
2
laser. The measurements taken as a function of gas composition, input power loading, and flow velocity reveal a strong similarity to electron beam-sustained machines. The relatively simple construction and operational characteristics exhibited by the device may render it industrially viable.
