Abstract
A laser-induced fluorescence experiment is described which was performed in the flow field of a 1-kW supersonic chemical laser. In the experiment molecular iodine vapor was injected into the chemical-laser cavity and made to fluoresce by Ar(+) laser excitation. The results obtained demonstrate that laser-induced fluorescence can be applied successfully to study mixing zones in chemical-laser cavities. The following potential seeding candidates for studying hot flows in chemical lasers are suggested, in addition to I2: popop dye vapor, SiH4, and H2S.
