The radiative decomposition of NaN3 particles using CO2 laser radiation has been studied to determine the threshold and decomposition efficiency. Both long-pulse (0.05–5 s) and short-pulse (1 μs) irradiation were used. A proposed model adequately

During the examination of a hafnium carbide film after exposure to an oxidizing atmosphere at 2060 °C, it was discovered that it contained a layer of fine-grained material, consisting of hafnium, carbon and oxygen, between the residual unoxidized ha

N 2 O laser gain profiles in a low-pressure Na-catalyzed N 2 OCO transverse-flow chemical laser have been measured for a variety of flow conditions. The small-signal gain depends on the CO/N 2 O ratio with a maximum of about 0.005 cm −1 measured

The decomposition of sodium azide, NaN3, has been studied using a pulsed carbon dioxide laser. Chemiluminescence associated with the decomposition has been measured with and, without, the azide surface in the detector field of view. Near the decompos
