 Abstract: A new experimental method is describe enabling detection of hydroxyl radicals (OH) by Laser- Induced Fluorescence (LIF) in high-temperature gasphase reactions. This is accomplished by means of a bidirectional optical fiber probe, which is of interest for applications where optical access is limited. An optical setup has been developed that allows simultaneous excitation and detection of fluorescence using one and the same fiber. Complications resulting from coupling as well as laser-induced scattering are addressed, and different fibers are compared with regard to core material composition and geometric collection efficiency. On this basis a suitable fiber is identified and OH detection and profile measurements are demonstrated in a premixed laminar flame as reference experiment.
