Spectroscopy of high pressure cesium discharge

Near UV, visible and NIR spectrum of Cs lamp has been studied in many experimental situations. We concentrate on the spectral region around resonance lines where numerous satellite bands appear. We followed the appearance of these satellite bands after the ignition. They first appear in emission, and then in absorption, due to the steady increase of cesium atom density. The origin of the satellite bands have been described \footnote{D. Ve\v za, R. Beuc, S. Milosevi\' c and G. Pichler, Eur. Phys. J. D, \textbf{2}, 45 (1998)}$^{,}$\footnote{R. Beuc, H. Skenderovi\' c, T. Ban, D. Ve\v za, G. Pichler, W. Meyer, Eur. Phys. J.D \textbf{15}, 209 (2001)}. We observed the satellite band intensity behavior in several different burners filled with cesium and xenon. In one burner made out of crystalline sapphire we observed interesting spatial distribution of entire visible spectrum, during evolution in time after the ignition. The intensity behavior of satellite bands in the near-infrared spectral region will be used in further development of the white light source with pulsed cesium high-pressure discharge.
