摘要: Abstract Cavity ring-down spectroscopy (CRDS) has been applied to the detection of oxygen atoms, on highly forbidden 1D2 ← 3P2 line at 630.030 nm. Results are presented for CRDS in a discharge flow system, which atoms prepared by microwave N2O/Ar or O2. Comparison concentrations determined and chemical titration NO2 is made. found be non-intrusive technique determination atom range 1014 cm−3 higher, with an estimated accuracy ⩽20%.
