Abstract VUV radiation generated by stimulated Raman scattering from H2 and tunable around 130 nm is applied to the detection of atomic oxygen produced in a flow-tube. Concentrations in the range to the detection of atomic oxygen produced in a flow-tube. Concentrations in the range of 1010 to 1011 O-atoms per cm3 lead to fluorescence signals that can easily be detected on a nanosecond timescale. We deduce that oxygen impurities generated by plasma-wall interaction in present-day tokamak experiments should be measurable with spatial and temporal resolution applying this vuv source.
