Abstract :The stimulated emission of radiation of atmospheric air gas was observed to be 337 nm at room temperature and it is the same wave-length as the nitrogen laser oscillation. The threshold voltage is about 9.5 kV, for 41 Torr at 1 Hz repetition. The optimum air pressure is 37 Torr at 13.8 kV, 36 Torr at 15.0 kV, 30 Torr at 12.0 kV, and 32 Torr at 15.6 kV. The output power ratio of the air laser to the nitrogen laser is about 1/300 — 1/400. The optimum air pressure for lasing shifts to the higher part as the applied voltage increases, and also the lasing area is drastically broadened. The pressure range of the lasing action is narrow compared with that of the nitrogen laser.
