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 at dry air gas using the laser-induced fluorescence method and OH transition [[A.sup.2][[SIGMA].sup.+](v' = 1) [left arrow] [X.sup.2][PI](v' = 0)] at 282 nm to monitor ground-state radicals.
