- Laser-induced fluorescence from carbon atoms, excited at the two-photon resonances around 280 nm, has been detected in fuel-rich hydrocarbon flames together with Swan band emission from the C2 radical, which was non-resonantly excited at the same wavelengths. The emission from the C atom and from the C2 molecule exhibited several similarities, indicating a possible common photo-chemical origin.

Imaging Measurements of Flow Velocities using Laser-Induced Fluorescence

Journal article (peer-reviewed)abstract
- Imaging velocity measurements along a line through a flowing gas are described. Laser-induced fluorescence from I 2 molecules, used to seed the flow, was utilized. A method of alternating counter-propagating beams from a single-mode dye laser, acting in the wing of the Doppler-shifted molecular absorption profile was used. Some improvements to the technique are also suggested.
