• Description: The evolution of the luminosity of the coplanar barrier discharge in the singlefilament mode was studied by the technique of cross-correlation spectroscopy. For the first time 3D-spatially and temporally resolved measurements of the radiation intensity of the second positive (at 337.1 nm) and first negative (at 391.5 nm) system of molecular nitrogen in this discharge type were realized. From these experimental data, the propagation of the cathode-directed ionizing wave (CDIW) is clearly seen. Surprisingly, a second ionizing wave (SW) has been detected, too. The results for the coplanar barrier discharge (CD) are compared with corresponding experimental results obtained for the volume barrier discharge (VD).
