Laser-Induced Fluorescence Image of OH Radicals for Atmospheric-Pressure Nonequilibrium Dry Air Gas DC Pulse Plasma Jet

OH radicals were successfully measured for the first time ever in an atmospheric-pressure nonequilibrium DC pulse discharge plasma jet in dry air gas using the laser-induced fluorescence method and OH transition [A
