Single-pulse laser-induced OH fluorescence in an atmospheric flame, spatially resolved with a diode array detector
Abstract:
Laser-induced fluorescence measurements of OH have been performed in an atmospheric stoichiometric CH(4)/air flame and in a highly sooting propane flame. The measurements were realized with a single 6-nsec pulse from a frequency-doubled dye laser pumped by a Nd:YAG laser and with a spatial resolution of ~25 microm. This was achieved by imaging through a suitably chosen filter set a section of the laser beam onto a gated and intensified diode array.
