Abstract
We report a pulsed combustion‐operated CO2 gas‐dynamic laser. A gas mixture is ignited in a combustion chamber to form heated CO2 and N2. The mixture expands through a supersonic nozzle, thereby causing population inversion in the CO2. Laser energy was about 20 J and pulse duration 0.3 sec. Variations of gain and pulse energy with gas composition and stagnation pressure are described.Keywords
