A fibre probe is developed to investigate the temporal development and the spatial distribution of the population density of argon 1s 5 state and the emission in the afterglow in a self-pulsing micro thin-cathode discharge at atmospheric pressure. The fibre probe with a diameter (125 µm) of about half the discharge diameter (200 µm) is moved along the discharge axis. A tunable diode laser beam at 696.73 nm at resonance with the argon 1s 5→ 2p 2 transition is coupled into the far end of the fibre probe. The spatially differentiated absorbance yields the axial distribution of the 1s 5 state. In addition, the fibre is used to determine similarly the spatially resolved optical emission of various argon lines. Both the emission and the absorption profiles confirm that, in the afterglow, the plasma is strongly localized inside the hole of the discharge. Qualitatively, the measurements agree very well with the results of a zero-dimensional simulation. The long living afterglow is related to the high population density of the metastable atoms.
