Abstract:

An experimental program was conducted using a small-scale, arc- augmented gas-dynamic laser with the objective of obtaining comprehensive data for evaluating theoretical predictions of optical gain for such devices over a wide range of potential operating conditions. Included among the program results were attainment of stagnation temperatures higher than those possible in ordinary combustion-driven gas-dynamic lasers, experimental evaluation of the homogeneity of the flow in this device and theoretical determination of the plenum gas composition from the experimentally measured stagnation temperature and pressure. A number of experimental difficulties were encountered during this program which limited the scope of the gain measurements obtained and thereby partially compromised the overall program objective.
