Abstract:
An investigation was made of a DF–CO2 amplifier. The chemical reaction was initiated by the photolysis of F2. A "guided" discharge initiated a discharge light source which emitted radiation energy of about 500 J in about 1 μsec in the absorption band of fluorine. The master oscillator was either a DF–CO2 chemical laser or a CO2–N2 laser pumped by a transverse discharge. When a D2:F2:CO2:He = 1:1:4:5 mixture was used in a DF–CO2 amplifier at atmospheric pressure, the output energy due to P(20) and P(22) transitions in the CO2 molecule was 150 J/liter and the chemical efficiency was ~7 %.
