Abstract
The laser-induced fluorescence spectroscopy on a micro-flow discharge with water electrode is carried out in order to investigate OH radicals. The branches P(2)(6), P(1)(4) and P(2)(3) of X(2) II, nu '' = 0-A(2) Sigma, nu' = 1 transition are used. Laser-induced fluorescence is used in order to estimate the density of OH radicals and density of water vapor in a core of the plasma. Sputtering yield of H(2)O from the liquid electrode is calculated based on experimental data. It is revealed that plasma core consists of 8-10% of water in both Ar and He discharges. The density of OH radicals in the micro-flow He plasma is higher than in the glow discharge with liquid electrode and in Ar micro-flow discharge due to constriction of the positive column and different mechanism of the OH radical production.
