The energy and spectral parameters of emission of a barrier discharge in chlorine and its mixtures with inert gases are studied experimentally. The barrier discharge in chlorine was homogeneous at pressures up to ∼ 9 Torr and its spectrum contained the 3∏2g -→ 3∏2u, 3∏2g → 3∑2u + and 1∑ u + → 1 g + bands of Cl2* molecules. After the addition of an inert gas, the 257.8-nm 3∏2g → 3∏2u band made the main contribution to the spectrum. The maximum efficiency and power of the Cl2 excilamp were obtained for the chlorineargon mixture and amounted to 0.7 % and 1.3 W, respectively.
