One of the most important methods of obtaining laser action, both from a technological and scientific viewpoint, is the chemically-pumped laser. The HN3 + C02 chemical laser has been modeled and an experimental investigation conducted to determine the existence of laser action. The analytical model has been used to predict the expected population inversion and laser gain for a range of pressures and various additives. The experimental investigation conducted for comparison with the model did not result in laser action. The increase in pressure for the mixtures investigated indicates the occurrence of an explosion. The lack of detection of laser action has been attributed to difficulties with alignment of the optical system and to signal noise associated with the flash circuit.
