Abstract

Exploding mixtures of oxygen with carbon monoxide, hydrogen, methane, and ethylene were examined for evidence of net optical gain in the 0.3-μ, to 30-μ wavelength region. Using a closed explosion vessel placed on-axis in a confocal resonator, no indication of optical maser oscillation was observed. Frequency selective dielectric mirrors were used to determine single-pass gain values in the 0.3-μ to 2.5-μ range. The results indicate net average loss, G ∼ 0.5, with a slight decrease in G values at the longer wavelengths.
