emission spectrum

Measurement, line fit and continuum background for data taken at 90 ns after the first emission (Figure 3 in paper).

Spatio-temporal plots for different N2 admixtures of the measured and individually normalized emission at 391 nm [(a) - (c)], of the time modulated component of the data shown in the first row [(d) -

Normalized (to the maximum value of each data set) spatio-temporal emission plots obtained from wavelength integrated and wavelength selective PROES (columns) at various N_2 gas flows (rows).
