Laser-Supported Combustion Wave Ignition in Hydrogen.

Abstract

Laser-supported combustion waves were generated in hydrogen at 45 psia. Propagation velocities were inferred from radiometric measurements and compared with values for air, adjsuted (according to Raizer's method) for differences in the physical properties of air and hydrogen. Coarse measurements of the radiant power in the visible region were made and compared with air plasmas produced by both pulsed and continuous wave (CW) carbon dioxide lasers.
